VS Will not install

[gordon_fan_24]

I have VS9, and it will not import DVD+VR (am I correct?) So I wanted to re-install VS7 SE DVD. When I put in the disc to install I get this error message:

Setup cannot find Video Studio installed on the computer

DUH!! I am trying to install it, if It was on the computer I wouldn't be having this problem. What is wrong now with the programs?

I have almost had it with Ulead, there products don't work properly, or just stop working all together for no reason (that was last week's issue, solved for now though) Now the program freezes every 5 mins, which makes it impossible to edit, if I'm constantly re-starting thte computer. Unless I can get this program to work, I think I will look elsewhere in the future, Dont get me wrong, when the program works, It's a great program, better than anything I've seen at the consumer level, but the problem is that it works 50% of the time
