Got an error while starting AVG

Hi,
I got this error while starting AVG software. See error below.

C:Program FilespmGmessiahStudio5_64Bitmessiah64LicenseUtilityms4_ClientlicenseUtility.exe
The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log for more detail.
I tried restarting it and got the same error. I tried starting other software like Firefox and games, but I got the same error message. I then tried rebooting my PC, but nothing has improved.
I researched the error in the internet and found out that I could view the event log. So what happens after this?
I couldn’t interpret what it said.
Can someone from this forum help me?
