OK, thanks for that info on the registry.
How about if there were some leftover registry items that might not be removed with an uninstall? Or perhaps any other Microstudio files or settings not removed during uninstall? Perhaps if I can do a total wipeout of Microstudio before reinstalling it, it might work. Has this ever happened before?
As for the ASPI, I can confirm, as before, that wnaspint.dll does not exist anywhere on my computer and that I installed the Adaptec drivers. See my other post with attached GIF showing that they are correctly installed.
You are correct that the software doesn't work. Whether it indicates my machine is "broken" I'm not so sure of, since, again as I've stated before, several other CD/DVD authoring programs work perfectly including Nero, iTunes, WindozMedia, MusicGiants, Quicktime, RealPlayer. That doesn't sound like a broken machine to me...
