Avast 5 Antivirus “Failed to start

Asked By 220 points N/A Posted on -


Can someone help me with the following problem? The problem is related to a problem of Antivirus. I have installed Avast 5 on my laptop with Windows XP. The installation is done correctly and there was nothing bad about it. But then I restarted Windows, I found a message as I took an outbreak of the screen and here is:

The application has failed to start because its side-by-side configuration is incorrect
C:Program FilesAlwil SoftwareAvast5AvastUI.exe
C:Program FilesAlwil SoftwareAvast5AvastUI.exe
The application has failed to start because its side-by-side configuration is incorrect. Please
see the application event log or use the command-line sxstrace.exe tool for more details.
And when I viewed the event logs I found the following message

"Activation context generation failed for "C:Program FilesAlwil SoftwareAvast5AvastUI.exe". Dependent Assembly Microsoft.VC90.MFC,processorArchitecture="x86",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="9.0.21022.8" could not be found. Please use sxstrace.exe for detailed diagnosis."

I tried to remove and uninstall Avast Antivirus often 'safe mode' and the other mode by using the aswclear5 utility but the problem persists. I don't know what to do now. If someone has to deal with this problem or has a solution for this problem I say please?

Thank you!

May be you are using trial version of Avast Antivirus. Some time trial versions of Avast Antivirus are not working properly because there are some restrictions to use for a few days. After the expire date it occurs some problem. My suggestion will be for you to just to upgrade the Avast Antivirus.

To upgrade the Antivirus you need to purchase the license. You can get the license from Avast Antivirus manufacturer website. After purchasing the license key, you just enter the original license key to start the application smoothly. You can buy this license key from Avast Antivirus company. It will be safe for your computer and no problem will create after the license key is entered.
