You know I find that this is kinda odd.
I bought the upgrade version of Pro 7 last year. It has both discs included. Is this something that they changed?

Anyway, I too am having problems with Mach 3 on my desk computer.
I am just trying to learn Turn.
I have no issues at all with my machine computer.
I was just searching for an answer and your issues were a bit different than mine.
I did install 32 Bit. I wanted all my other stuff to work on it and I went through software compatibility crap with Vista.
Good luck with it though.

Thanks!

I bought my 64 bit version at a computer show and it was just the one disk. I got my 32 bit version and everything is working fine. I am glad I did this and do not have any more problems like I did before. Now all the problems I have are of my own error.
