Works for me under Vista Ultimate sp2 32bit and a Q6600 processor. During the start up splash screen there is a message "Multiproceesor detected" and all four cores are used. I didn't need to change any settings, it is wholly automatic. Perhaps it's an XP issue.
Insanity is hereditary, you get it from your children
To verify what the splash screen may indicate, I would launch the Task Manager, then view Performance.
With the Task Mgr running initiate a CPU intense task like a Render, or Burn-to-Folder under Share.
Then see if in fact all 4 CPU Cores are being utilized, or just one.
On a Quad Core CPU, you should see activity across all Cores with the Task Manager.
If only one Core is Active, perhaps a Repair or Reinstall may fix.
Or you may have to contact Adobe Support at some point, and open a ticket...
Welcome to the forum.
I cannot imagine why PrE 7 would not detect all processors. My copy of PrE 4 sees all four processors on my Quad system w/ XP-Pro XP3.
I am upgrading to Windows 7 so I'll see what results come from those efforts.
Did it work for you?
I did try to repair XP, I did not see any difference. I will be upgrading to Windows 7 in a week or so. I will be doing a clean Install for Win 7 anyways, I'll post back if the upgrade and the re-install of Premier is effective.
Thanks for the follow up.
Shawn, in my post above, when I mentioned a Repair, it was meant for Premier Elements.
If you've confirmed via Task Manager that all Cores are not utilized, perhaps a Repair, or re-install of PE under WinXP, may help the cause.
To Repair PE, don't uninstall it, but just re-run the Installation and follow the link for Repair.
If you planned to go to Win7 in either case, then I guess it makes sense to load your OS of choice first, then see if PE still has an issue...
I am not sure if PE 7 will work on Win 7.0 or not, since Win7 was not around at the time when PE 7 was released. So, I won;t be surpirsed if it has some issues on Win 7.
You should have no problems at all using Premiere Elements 7 on a Window 7 32-bit machine.
