Completed my first build for my son as a Christmas present. Installed 64bit win7. Go to install MSI driver cd and I get a error message " D:/is not a valid win32 application" so I check to make sure that I am running 64bit and I am. I have no internet connection no sound or anything..lack of drivers I guess. The Specs are, AMD A85600k CPU / MSI a78-e35 MB. Anybody help me out? And Merry Christmas!
