Sometimes users working with the Windows 7 operating system encounter an unpleasant problem, which is that when a certain application (most often a user) starts up, the so-called CLR20r3 error appears when the program starts. By far not everyone knows what it is and how to eliminate such a failure, so this problem needs to be addressed in more detail. The solutions proposed below can be applied not only to the seventh modification of the system, since they work equally well in OS versions lower or higher.
CLR20r3 error when starting the program: what is it, failure or not?
To begin with, this failure is mainly characteristic exclusively for Windows of the seventh version. In other modifications, it is extremely rare. Why this happens is not known for certain, but the fact, as they say, remains a fact.
What is most interesting, in Windows 7 the CLR20r3 startup error is most often observed when trying to start the executable files of games or applications related to multimedia (the same "Media Center" or the corresponding player). The failure itself is positioned as a malfunction of some specific platform, which is used when opening the corresponding programs.
Causes of the error
The CLR20r3 error when starting the program is not critical in itself (the system continues to work as usual), but on user applications this is manifested to a rather high degree, and for some reason selectively (one program can work without problems, the other can not start at all) .
As for the reasons for the appearance of such a failure, among the main ones, one can especially distinguish the following:
- Viral exposure.
- Violations of the "Update Center".
- Outdated or damaged .NET framework.
CLR20r3 Windows 7 crash: how to fix
Now we turn directly to the solutions that will allow us to get rid of this failure or its annoying message and restore the functionality of the "crashed" applications. Consider how to fix the CLR20r3 error (Windows Media Center gives it, any other program or game, it doesn’t matter), based on the above reasons for its appearance.
To begin with, it’s worth completely checking the computer for viruses, but you do not need to use a standard scanner (it could already have missed the threat), but some portable utility that does not require installation on a PC (for example, Dr. Web CureIt!).
For deeper cleaning, if the viruses settled deep in RAM, the optimal solution would be to boot from a disk or flash drive with the Kaspersky Recure Disk utility recorded on them. This program has its own bootloader, and therefore starts even before the operating system (the removable device itself is bootable, only it must be set first in the BIOS settings).
If threats are not detected, and the CLR20r3 error appears again when the program starts, it may very well be that the system simply does not have the necessary updates. There is a likelihood that during the automatic update they were not fully loaded or the Update Center failed to install them.
In this case, it is necessary to check the available updates in manual mode and install everything found with the subsequent reboot of the computer system.
If for some reason the manual search or installation is not carried out, and the system displays 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 to open the parameter editing menu , stop the service, set the startup type to shutdown, save the changes, restart the system, re-enter the specified section and enable the service by setting the automatic startup type. After that, if the automatic update does not start, you can check for updates again yourself.
Guaranteed troubleshooting method
Finally, let's move on to the most basic cause of the failure. Too many games and multimedia applications require the .NET Framework in the system to function correctly. Its absence, obsolescence or damage in most cases and provokes the appearance of such a failure.
You can correct the situation quite simply by downloading the latest version of the platform from the official Microsoft resource and integrating it into the system. Just in case (although this is not necessary) at the same time, you can update the version of DirectX. But you do not need to touch the MS Visual C ++ Distributable component, since many applications install it on their own and different programs require different versions of the package (at the same time there may be several of them in the system, regardless of the year of development and release).
Conclusion
That's all with regard to fixing errors when starting games and multimedia programs. In most cases, reinstalling the main platform helps, although the impact of viruses or crashes during the installation of the necessary updates for the system and some update updates programs cannot be reset. Separately, it is worth saying that the .NET Framework, even with the active automatic update of the system, is not always updated. Therefore, it is better to download the installation distribution kit and install it yourself.
