When i installed my computer fresh, i installed programs like Visual Studio 2008. I ran my program from the debug directory and it worked fine; no errors. I was testing to see where this error had been coming from. I "merged" some file with the registry, then re-tested the program. The debug came up with this message (The application was unable to start correctly) and VB came up with The application was expected to contain an assembly manifest or something. Do you think that modifying the registry causes this error? And any way to fix it?
