Missing personalization infopoints to permissions/ user privileges issues which are to be expected with such old versions on contemporary operating systems. Run as admin, turn off security stuff, try compatibility modes. Actualyl burning the discs will of course work, but you might look into simply mounting folders/ disc images as virtual drives e.g. using Daemon Tools Lite or your disc burning software's own disc mounter.
Thank you for your response. I have tried working with compatibility modes, but with no success. Hadn't tried security aspects before, but doing so in response to your post didn't seem to help either. I will try the virtual drive idea. I take it that would mean running each .exe file to extract to different folders, then mounting the first folder (the one made from CreativeSuiteCS2Disc1.exe) and running it? Or do I have to mount all 3 folders before running the first?
