I just turned on my sony vaio laptop that runs windows 7 home premium and when i try to run any type of application, it shows an error saying "No such interface supported" I've tried everything in the forum and nothings working.. I can't get into regedit.exe to fix the registry and the error pops up when i try to do a recovery, and also i dont have a back up... the weird thing is that it can run programs through other ways.... I was able to open itunes by manually clicking a song, and I had to manually turn on my wireless hardware to get internet connection. Please help..!!
