I'm trying to upgrade or install osr2 onto a laptop without a cd-rom. The laptop has win95 on it already. I copied the companion cd to the laptop's hd. I also copied setup.exe and winsetup.bin. When I run setup, it starts to go through and then it says that my computer already has an OS installed which cannot be upgraded by this version of setup. I know I did this before and it worked... what do I do?
