I am a bit of a duffer about this stuff so be kind....I have some CD Roms that I need to install but you have to have Windows to run them and I have a Mac running OS X - can you get Windows for the Mac or is there nothing I can do but use someone else's PC?
if you really need those programs, there may be mac versions of the programs you are after.
you can't use them on a mac, because windows-based pcs use x86 processors (intel ones, etc.), and macs (currently) use powerPC chips. the two are different, so its like trying to speak English to the Japanese: its not gonna work.
some programs, however, come on hybrid CDs that contain both the mac and windows data. see if your CDs are of that kind.
