Get at least 2 other SATA disks, maybe even an additional smallish one for OS & programs. 1 TB for OS is a waste of space. 150+ G is more than enough.
A single 1T drive is NOT good for video editing... what I am going to build is near the top of my notes page http://www.pacifier.com/~jtsmith/ADOBE.HTM
As far as I know (could be wrong) if you have Win7 Pro or higher you may run a virtual XP computer, which should work for P1.5 but you will have to search around at Microsoft to find their site where you may download the software to do that
The one thing you do NOT want to do is use partitions on that 1T drive to "create" different drive letters... that is VERY BAD for video editing
Dont get the HOME version of windows 7
If i recall correctly you can only run XP from the Pro version of windows 7
There may be other things wrong with the setup of the computer you choose but just wanted to point the XP issue before you bought it and then learned you didnt have the option later.
Chances are slim with a 5 year old program.
Welcome to the forum.
My first guess would be that there will be issues. Even PrPro 2.0 had some with Vista, though many did get it functioning. With an even older version, things might get tricky.
Now, reports are that Win7 does a much better job at handling older software, than Vista did, so with Win7 Pro, one might have better luck, than Vista users did.
If you try it, and get it to work, please update this thread, to help others.
I have been unable to run PPro 1.5 with Windows 7 without running it in a compatibility mode, and even then I have trouble rendering video down to Adobe Media Encoder.
I upgraded to CS4, and works great. That's my suggestion. I never tried
PPro 1.5 in Windows 7 so I can't really help you.
