Hello, I purchased Driver Cleaner yesterday and cannot run it due to a runtime error. When I run the program I get the error message: "unable to find a version of runtime to run this application" I have XP Service pk 3 and .NET Framework 4 When installing the program it couldn't detect the version of .NET Framework I was running but I have version 4 installed. I have repaired .NET Framework but I still get the same error. Any help would be appreciated. Thank you.
