New install on Vista 32bit Ultimate
Uninstalled the previous version and installed Photoshop elements 7.0 and Premiere Elements 4.
When I try to run Premiere it crashes.
I have run Photoshop elements, and I created a new catelogue as suggested elsewhere in relations to this error.
I would go to Windows Update and ensure I had even the non-critical updates. Then I'd ensure I had the latest version of Quicktime.
Then I'd uninstall Premiere Elements and run a registry cleaner. CCleaner is great. Windows Advanced System Care, from IOBit software, is also free and not only cleans your registry but it clear temp and other junk files.
You might also want to go to C:/Documents and Settings/[Owner}/Application Data/Adobe and change the name of the Premiere Elements folder to "Premiere Elements OLD". Then reinstall the software.
All if this is assuming you've got plenty of RAM, a fast processor and at least 30 gigs of free, defragmented space on your C drive.
