It could well be related to the fact that you're running it on a 64-bit operating system.
But it could also be a benign error code. That occasionally happened with an earlier version of the software also. It shouldn't affect the program or any work you have in progress.
But you can certainly let Adobe know it's there.
Thanks for your answer. However, I'm not actually getting any type of error code. But when I quit the application, one core of my CPU jumps up to full usage, and in my process list, I see the Adobe Premiere Elements.exe process still running and consuming that CPU.
I have run many 32-bit apps on my 64-bit OS, and have yet to see this type of behavior.
Is it possible that Premiere Elements 8 does not yet fully support Windows 7? Anyone from Adobe on here that can answer that question?
To get an answer from Adobe, you'll need to contact Adobe. This is a user-to-user forum here.
Meantime, remember that although you are using Window 7 RC, it's still not a final release version, so they could still be working these minor bugs out -- even as third-party driver and firmware providers work to update their support for it.
When many programs shut down, especially NLE's, there is a great deal of "cleanup," that they must perform. There are a lot of temp files, that are needed for editing, Exporting, Burning, etc., that need to be removed. This is likely what you are seeing, especially with no error messages.
As for Adobe presence, the closest thing that you'll find is that red and white A logo on the upper-left of the forum pages. We're all just users here.
Actually, I am using the Windows 7 RTM version from my MSDN account. So it is the final release. I will continue my testing and see if I can figure out what it is doing. I left it running for several hours last time and it still wouldn't stop...
