So I restart in Safe Mode, I have the disc in the drive, and to cut a long story short, it doesnt work. I looked through the batch file, it keeps trying to use the "extract" command, but that isn't recognised, says command prompt. I am running winxp, and it's formatted in fat32. Everything seems to work fine apart from the EXTRACT command, and at the end the: %SystemRoot%\System32\rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 dxvfix.inf doesn't work either. Anyone got any ideas for me, it's really annoying me... Edit: I don't really need to go back to 8.1 other than to install a program. If any of you have a way to trick Windows XP into thinking that it has got DX8.1 that would help just as much.
