Hello guys, Several days ago I encounterd the error when trying to open "firefox" or other programs that seems to require this side-by-side configuration. I did some research in Google some suggested to deinstall and reinstall Visual C++ 2005 SP1 and Visual C++ 2005 SP1 but without any success. I ended up with deinstalling Visual C++ 2005 SP1 and only installed version 2008 and 2010. Some programs are still running smoothly as intended. Is there any way to fix it? I try to avoid a clean installation of Win7 and fix it somehow but I couldn't find any working solutions so far. It would be nice if someone has a solution for this. THanks in advance
