Hi, does anyone know if there is a compatibility issue with Premiere CS4 and Windows 7 home premium? I keep getting "Error 1603. Fatal error" during installation.

I can't answer the question directly, but here as an Adobe page on Win 7:
Installing and using Windows 7 with Adobe applications (http://kb2.adobe.com/cps/508/cpsid_50853.html)

Since we're on the subject, i'm purchasing Windows 7 tonight or tomorrow...

I'm under the impression, that the PRO version might be best suited for the CS4 suite..

Does anybody want to chime in, as to which Windows 7 64 bit is preffered?

Thanx..

I've run CS4 under both Home Premium and Professional, both 64 bit. I don't know of any Windows features CS4 would need beyond Home Premium, but the features in the higher versions won't harm CS4.

I know Premium is limited to 16GB of ram and both Pro & Ultimate are far higher.

And I think Premium is limited to one CPU whereas I know Pro/Ultimate are limited to 2.

Some video gear needs Pro as a minimum (such as some Matrox products).

Steve,

Win7 Pro uses all cores. In my case all 8 of them. I believe the current limit is 16 cores.

This picture shows all cores used during encoding with AME. Sidenote: Rendering the timeline does not appear to be using HT, so previews only use 4 cores on my system, but that may be caused by the fact that my CPU usage during rendering never was more than 12%. During encoding it was far higher.

Sorry if I misunderstood you. Reading your message again it looks like you are talking about physical CPU's, not cores.
