Tried deleteing in safemode, from the command prompt, I just don't know what to do. It says it's being used by another program. The file is an installation file for soundblaster live drivers. It was for my brothers computer cause I was reinstalling windows. The file has nothing to do with my soundcard. It's very strange why I can't delete it. The permissions look fine also. It's very annoying! I try to keep my computer as clean as I can, so I don't know what's going on. Any help is appreciated.
