Surely, many fans of modern computer games, when installing them on a computer, faced a problem when the installation is about to end, and instead of successfully completing, the system displays a message like “Unarc.dll returned error code 6”. What is the reason and how to fix this situation, now it will be shown on the simplest examples.

"Unarc.dll returned error code 6" failure: what does it mean and what is the reason?

Before you begin troubleshooting failures associated with this type of error, you should understand the reasons for their occurrence. It is believed that in most cases they occur only when downloading from the Internet and using unofficial installation builds, which are commonly called Re-Pack.

Unfortunately, most often these are not "native" distributions of games, but custom sets, in which some important components may be missing or damaged. In addition, as a rule, they are presented in the form of archives, with which many problems can also arise.

The decompressor program and two dynamic libraries - ISDone.dll and Unarc.dll are responsible for installing games. Error code 6 with different types of failure description can indicate the most common causes of problems, among which are the following:

damage to the downloaded archive with integrity violation;
creating an archive with a higher version of the archiver than the one used for unpacking;
virus infection of archive contents;
failures in dynamic components.

Errors in the components of the installation distribution when installing games

The most unpleasant situation for a gamer is the appearance of an error at the final stage of installing the game. The installation progress may already be 95-99% complete, but it is at this time that a critical failure appears.

The reason for this is tritely simple. Error 6 is thrown by the Unarc.dll component when unpacking and installing the last missing components is impossible. As a rule, these are the archives whose contents are extracted last. In official distributions, there are no problems only because the set has its own decompressor, the files are presented as self-extracting archives, or during the unpacking process, the installer accesses the archiver installed on the system, which corresponds to the modification of the program with which the archive was originally created.

At the same time, in the description you can often find the phrases “Unarc.dll returned error code 6. Error. File read operation failed" or "Decompression failed". The first description says that the installer cannot read (recognize) the file, the second one indicates that the archiver cannot decompress the content.

Unarc.dll returned error code 6: how to fix the crash in the easiest way

The first and easiest way to troubleshoot a corrupted archive is to try downloading it to your computer again. It may very well be that he simply did not load.

If re-downloading does not give a positive result, and the archiver in the error message mentions a data reading failure, you should look for an undamaged (whole) archive on another resource and download it to your computer.

Troubleshooting Archivers

On the other hand, when the installer accesses the archiver installed on the system, or the user extracts the contents of the archive during the installation process on his own, the situation with the appearance of a warning that Unarc.dll returned error code 6 can also occur.

Most often, the problem is that the version of the compression program is lower than the one with which the archive was packed. The simplest example is an attempt to unpack archives created using WinRAR version 5 with a similar application, but version 4. The way out of this situation is to install the desired version of the archiver or replace it with another equivalent one (WinZIP, 7-Zip, etc.) .

By the way, with regard to packing an archive with 7-Zip, sometimes non-standard enhanced compression methods can be used that WinZIP and WinRAR do not support. In this case, the extraction of the content must be done by the original application.

Virus infection problems

The viral impact cannot be underestimated either. Both the archive itself and the dynamic libraries involved in the game installation process can be infected.

In the first case, before unpacking, you should check the desired archive for viruses, in the second, you should perform a comprehensive scan of the entire computer system by activating in-depth analysis.

Fixing failures of dynamic components involved in the installation process

Finally, the message "Unarc.dll returned error code 6" can also appear in the event of a failure of the dynamic components themselves, due to a critical impact on the operating system (incorrect shutdown, power surges, system component errors, etc.).

For such cases, there is also a solution. Since such failures cannot be manually corrected (even if the original libraries copied from another computer with a similar OS or downloaded from the Internet are integrated into the system), they should be restored. We do not consider system rollback, because the components could have been damaged a long time ago, and there is no checkpoint for recovery.

You can check the system with the sfc scannow command, which is entered in the appropriate console. The easiest way is to use special utilities like DLL Suite or Microsoft Fix It!, which will do all the operations automatically without user intervention.

Conclusion

In conclusion, the topic remains to be added that the most frequent failures are precisely the errors of archived data, so it is better not to use all sorts of re-packs, but to install your favorite or favorite games using official distributions. Only in this case it is possible to guarantee that the installation will be successful, and there will be no problems during the installation process.

Just in case, archiving programs should also be kept up to date, because new versions, with which archives are created, require more powerful compression using updated algorithms, and outdated modifications may not support such technologies.

Finally, issues related to damage to the RAM sticks, and any other physical failures, were not considered here.

Malfunctions, breakdowns of heating equipment are inevitable. Depending on the model of the Buderus boiler, automation notifies the user of a problem with a code on the display or by flashing the corresponding indicator light.

The article discusses the causes of error 6a and gives practical advice on troubleshooting.

On a note!

Control boards of imported boilers react to changes in the parameters of the electrical network. Before you start troubleshooting Buderus or your heating system, it is recommended that you do the following:

check the mains voltage. The Buderus passport indicates 230 V, and with a significant discrepancy, automation may malfunction and errors may appear on the display;

Checking the mains voltage with a multimeter

make sure the boiler is grounded. Poor contact at the wire connection point may cause the fault code to be displayed;

press and hold the OK button for 10 seconds (if it is provided for this Buderus model) - the error should disappear;

Press the OK button on the Buderus U072 boiler control panel

turn off and restart the boiler (Stand-by button on the front panel). If code 6a is not removed, you need to deal with the reasons that trigger it.

Press the Stand-by button on the Buderus U072 boiler control panel

Error 6a(2nd LED blinking) – No burner flame.

The code is generated in the Buderus control board in the absence of current through the electrode of the boiler ionization sensor. There are several probable reasons, and in order to reduce the time for troubleshooting, it is advisable to adhere to such an algorithm of actions.

Step 1- line testing

Easy gas check

If the object has a gas stove, it is enough to light all the burners. It will immediately become clear that the pipe is not blocked, and the pressure of the "blue fuel" is normal (by the intensity and uniformity of the flames). If the result is negative, you will have to look for the cause.

Check what

Shut-off valves . During a long absence, the owners usually block the pipe, and then forget about it. In private houses, such a protection element as a shut-off valve is installed.

Cranes with a yellow handle are designed to shut off gas in the pipeline

For gas pipelines, a normally closed device is used. Therefore, even with a short-term power outage, the mechanism will work and block the line. The boiler will stop and the Buderus automation will show error 6a. Armature is cocked manually.

Filter . Neglecting the frequency of its maintenance leads to the fact that pollution affects the intensity of gas supply: Buderus stops and gives an error 6a.

Gear Condition (in case of autonomous gas supply). The deterioration of thermal insulation, insufficient insulation of the outdoor cabinet, the head of the gas tank lead to icing: the fuel does not reach Buderus.

The reducer is connected to the gas cylinder

Tank full. Limiting volume production reduces the gas pressure to a critical value. The boiler will not start, and the automation will show an error.

If no defects are found, and gas is not supplied to Buderus, the probable cause of code 6a is the meter. But it is sealed, so you have to call the master.

Step 2– equipment testing

Ionization sensor

There are several reasons why it does not signal the presence of a flame to the Buderus control board.

Electrode contamination. It needs to be cleaned of soot, dust, and error 6a will disappear.

Breakage, short circuit of wires, poor contact in connectors, oxidation of plug lamellas - it is easy to visually identify and eliminate.

Wrong position of the electrode: it does not see the flame. It happens when the user independently serves Buderus. For example, when cleaning the nozzles of a boiler burner, the sensitive element is touched by an inaccurate movement. You can determine by the spark during ignition: is it sufficient to ignite the gas, where exactly does it hit.

gas fittings

Buderus boiler gas valve

Measuring nipple (pressure at nozzles)
Adjusting screw for maximum gas flow
Lid
Adjusting screw for minimum gas flow
Connection for measuring the supplied gas pressure

The only thing you can do yourself is to check the integrity of the connected wires. It is not recommended to adjust the valve, especially disassembling the assembly - this is the prerogative of a professional.

The instructions for the Buderus boiler describe the technology for setting the fittings, but it is better not to engage in amateur activities - without proper knowledge, practical experience cannot be done competently. There will be problems with increased gas consumption, frequent malfunctions of the Buderus boiler, and errors on the display.

Burner

With a long idle time of the heating unit, the holes of the nozzles become clogged with dust, during its operation, the smallest particles of soot settle on them (if the fuel is of poor quality, the fittings are not adjusted). Using a brush (for example, a toothbrush) and a vacuum cleaner, error 6a can be eliminated in a few minutes, and the boiler will resume operation.

Step 3- chimney check

Lack of oxygen, blocking the air supply to the burner can cause error 6a of the Buderus boiler. First of all, you need to check the outer part of the coaxial chimney. The formation of ice prevents the air flow, error 6a appears, the boiler stops.

If the user encountered this problem after the first start-up of Buderus, it is advisable to invite a specialist. Probable causes of error 6a: incorrectly calculated channel diameter, route length, illiterate scheme.

For units with an open chamber, the vertical (accelerator) part must be at least the length recommended by the manufacturer (depending on the boiler power). Don't figure it out on your own.

The measures taken to restore Buderus performance may not eliminate error 6a. In this case, the fault must be sought in the boiler control board.

It should also be checked when the unit stops a short time after ignition. 99% of the reason is in it; at home is not being repaired, it is changing. You can restore the module by flashing it, but only at the service center.

Ensuring the stable operation of the boiler, reducing the risk of errors is achieved by connecting Buderus through a UPS.

Uninterruptible power supply SKAT

Stabilizers strongly recommended by managers of retail outlets in the event of a power line break, interruptions in power supply will not help - they only smooth out ripples, maintaining the voltage value within 220, with slight deviations.

There are batteries in the power supplies for heating boilers, and in any case the equipment will not stop.

The operation of Buderus with an open chamber is affected by the ventilation in the room. It is easy to check by increasing the thrust: for example, open windows, doors. If the reason is a lack of oxygen in the combustible mixture, error 6a disappears.

A rare case known from practice: the appearance of such a code was initiated by a glass crack on the Buderus panel (“window” of the boiler combustion chamber). During visual inspection, you need to make sure that there is no mechanical damage, tightness around the perimeter.

The article discusses those causes of error 6a Buderus, which are eliminated independently. Experimenting, expanding the circle of troubleshooting, guided by the advice of various experts, is not recommended.

Imported gas boilers are expensive, in addition, there are differences in the designs of modifications. Enough arguments to understand: no result - to a professional.

If you have experience on how to fix error 6a in a Buderus gas boiler or a solution based on your experience - write in the comments to this article, we will try to consider your option and analyze it in detail in this article or one of the following articles.

Good evening, I'll start with a little preface. I drove my Allroad 2010 onwards. to a friend to eliminate all sorts of chips and scratches, i.e. to painters and tinsmiths, I arrived in an absolutely working car, I arrive in a week, we drive out into the street to compare the color of the paint, broads, the number plate light does not light up and the windshield wipers do not work. Today I brought a laptop and "Vasya" 16.9.0, I connect it and the following errors come out:

Can anyone tell me I would be very grateful and where this sensor is located

Fans of downloading hacked games and programs from torrents, called RePacks, may encounter the error "Unarc.dll return error code - 6". By the way, the number in this message can be absolutely anything, from 1 to 12, this does not change the essence, the cause of the occurrence is always the same.This article will discuss how to fix this error in order to install the downloaded application normally.

What is the error

Before discussing how to fix the error "Unarc.dll return error code - 6", it is worth understanding the reason for its occurrence. And she's pretty simple. An error occurs while unpacking the archive, due to which the process cannot be completed. It can be caused by various reasons, but most often the fault is the lack of the necessary archiver on the computer or its version. This phenomenon can be very easily corrected, which will be discussed below, but there are also so-called critical errors that cannot be corrected.

Critical error

Immediately it is worth identifying a critical error. If you have it, then you should see a line in the message that contains the words filed CRC check. Unfortunately, it cannot be corrected. That is, you will not be able to install a game or program by performing manipulations on a computer. However, there is one way that can help. In the article, he comes first in line, so if you find that you have a critical error, contact him.

Not a critical error

But along with a critical error, there is also a non-critical one, and, fortunately, it happens more often than the first. To understand what it is, you need to look at the line that comes after "Unarc.dll return error code - 6", there should be an inscription: file read operation failed. If you see it, then this means that one of the following methods will help you fix it. But you should also pay attention to the fact that they must be performed in the order of the specified queue - this will increase the chance of success. And some of them work only in conjunction with others, so read the instructions carefully and try not to miss anything.

Remedy #1: When the archive is corrupted

So, it's time to start the story about how to fix the error "Unarc.dll return error code - 6". Now it will be told how to fix the error if it is related to a corrupted archive. By the way, it is this method that can help in case of a critical error.

The fact is that in some cases you can download an archive that is "broken". Moreover, it can be damaged both during the loading itself, and be like that from the very beginning. In this case, installing the game or program will not work in any way, but only downloading a new RePack will help.

Remedy number 2: installing archivers

It has already been said above that a more common cause of the error is the lack of the necessary archiver that could work with the format that is embedded in RePack itself. The fact is that many authors who make these archives use "exotic" archiving methods to reduce their weight as much as possible. The solution "Unarc.dll returned error code - 6" in this case is quite simple. You need to download and install on your computer the latest versions of two archivers: 7-Zip and WinRar. After installing them, the error should disappear.

Remedy number 3: disable antivirus and other security features

Although the presented error occurs due to the lack of the necessary archivers, this is not the only reason. And installing third-party programs can not always help. Sometimes the antivirus or other Windows protection tools become the culprit. Now we will tell you how to fix "Unarc.dll return error code - 6" if the antivirus is guilty.

If you have installed an antivirus from a third-party manufacturer, then check the website for how to disable it. If you use Windows Defender, then go to the control panel, go to the appropriate section and disable protection in the settings. You can also disable the firewall in the control panel - it can also cause an error. By the way, after installing the game or program, protection tools can be turned back on.

Remedy number 4: obtaining rights

You have disabled the antivirus, but what to do with "Unarc.dll return error code - 6" if this message still appears. Now we will consider a fairly simple method for fixing this problem. As mentioned at the beginning of the article, some methods are best used in tandem with others, this is just such a case - use it with the previous one.

So, disable system protections and try to run the installer with administrator privileges. That is, right-click on it and click on "Run as administrator".

Remedy #5: Increasing swap space

Unfortunately, the solution to the problem is not always as simple as in the previous case. Perhaps the error occurs due to the small size of the paging file. Fortunately, you can increase it at any time. Now let's figure out how to do it.

Open system properties by right-clicking on the "My Computer" shortcut and selecting "Properties".

In the left pane, click "Advanced system settings".

In the window that appears, go to the "Advanced" section.

Enter performance settings.

Go to the "Advanced" section.

Click on "Change".

Now in the window that appears, check the first item, select the disk with the paging file and specify the maximum size equal to your RAM, and then save the changes.

Remedy number 6: increase RAM

Unfortunately, the solution to the error "Unarc.dll return error code - 6" may simply not be feasible using the tools of the operating system itself. Sometimes intervention in the system unit is necessary. The fact is that for correct unpacking, there may not be enough RAM, in this case only increasing it will help. But it is advised to purchase this type of memory only if all other methods have not helped you.

Solution #7: Replacing Library Files

Finally, you can try to replace the dynamic libraries themselves, which are used during the installation process. It is necessary to change ISDone together with Unarc. This is made as easy as possible:

Move the downloaded files along the path C:\Windows\System32 or C:\Windows\SysWOW64, depending on the bitness of your system.

Press Win+R.

Run the regsvr32 isdone.dll and regsvr32 unarc.dll commands.

Perhaps after these manipulations the problem will disappear.
