Error CLR20r3 when starting the program: why it occurs, and how to fix the failure

Sometimes users working with an operating systemsystem Windows 7, faced with an unpleasant problem, which is that when you start an application (most often a custom application), a so-called CLR20r3 error appears when the program starts. What is it and how to eliminate such a failure, know not all, so this issue should be discussed in more detail. The solutions offered below can be applied not only to the seventh modification of the system, since they work equally well in OS versions lower or higher.

Error CLR20r3 at program startup: what is it, crash or not?

To begin with, this failure is mainlyis specific only for Windows namely the seventh version. In other modifications, it is extremely rare. Why this happens is for certain unknown, but the fact, as they say, remains a fact.

What's the most interesting, in Windows 7 startup errorCLR20r3 is most often observed when you try to start executable files for games or applications related to multimedia (the same "Media Center" or the corresponding player). The failure itself is positioned as a violation of the work of a specific platform, which is used when opening the corresponding programs.

Causes of error

Error CLR20r3 when the program starts by itselfit is not critical (the system continues to work in the normal mode), but it appears in user applications quite high, for some reason, selectively (one program can work without problems, the other can not run at all).

As for the reasons for the appearance of such a malfunction, among the main ones one can especially single out the following:

• Viral influence.
• Violations in the work of the "Update Center".
• Obsolete or damaged .NET framework.

Windows 7 CLR20r3 crash: how to fix

Now let's move directly to the solutions,which will get rid of this malfunction or its annoying message and restore the working capacity of "departing" applications. Consider how to fix the error CLR20r3 (Windows Media Center gives it, any other program or game, it does not matter), based on the above reasons for its appearance.

To begin with, it's worth checking the computer completelyfor viruses, but to use this you need not an established standard scanner (it could already miss the threat), but some portable utility that does not require installation on a PC (for example, Dr. Web CureIt!).

For deeper cleaning, if the viruseshave settled deep in the RAM, the optimal solution will be to boot from a disk or a flash drive with the Kaspersky Recure Disk utility written to them. This program has its own bootloader, so it also starts before the operating system (the removable device itself is bootable, only it must be set first in the BIOS settings).

If no threats are detected, and the error CLR20r3when the program is launched, it will appear again, it may very well be that the system simply does not have the necessary updates. There is a possibility that when they were automatically upgraded, they were not fully downloaded or when they were installed, the "Update Center" failed.

In this case, you need to check the available updates in manual mode and install everything found with the subsequent reboot of the computer system.

If for some reason a manual search orthe installation will not be performed, and the system will generate an update error, you will have to use the services section (services.msc in the "Run" console), find the "Update Center" line there, double-click the parameter editing menu, stop the service, set the startup type to disable , save changes, restart the system, re-enter the specified partition and turn on the service by setting the automatic startup type. After that, if the automatic update does not start, you can check for updates yourself again.

Guaranteed method of problem solving

Finally, we turn to the most basic reasonthe occurrence of a failure. A lot of games and multimedia applications require the presence of the .NET Framework in the system for correct operation. Its absence, obsolescence or damage in most cases and provokes the appearance of such a malfunction.

It is possible to correct the situation quite simply,downloading from the official Microsoft resource the latest version of the platform and integrating it into the system. Just in case (although it is not necessary), you can also update the DirectX version. But you do not need to touch the MS Visual C ++ Distributable component, since many applications install it independently and for different programs different versions of the package are required (at the same time there may be several in the system, regardless of the year of development and release).

Conclusion

That's all, as for correcting the error whenStart of games and multimedia programs. In most cases, the reinstallation of the main platform helps, although the impact of viruses or crashes when installing the updates necessary for the system and some update programs from accounts can not be reset either. Separately it is necessary to say that the. NET Framework is not always updated with automatic automatic update of the system. Therefore, it's better to download the installation distribution and install it yourself.
