have been trying to install Windows 2k Pro and Windows XP to my roommates computer and everytime I start installing it, I get this: The file dsound3d.dll was not copied correctly. The file Setup placed on your hard drive is not a valid Windows XP system image. If you are installing from a CD, there may be a problem with the Windows XP CD. Retry, Skip, Quit, etc... Please help!!! I've gotten this message everytime I set up Windows on this computer.
