Avast UI not working. Need Help

So I just installed Avast Free Antivirus on one of my computers. The installation went fine until finish.

This is when it gets wierd. When installation is done, nothing pops up.
When I try to double click on AvastUI.exe, nothing happens. Not even a window popup. No error message. Nothing…

Task manager shows avast is running, services shows the same.

I tried to do a repair, a clean reinstall, but to no avail

Computer is Windows 7 32bit
Any help is appreciated

  • Which version of Avast Free…?
  • Other security related software installed…?
  • Which AV(s) did you use before Avast…?
