Welcome to the forums. Please try hidden admin account and try to launch the product. Once it is launched then try launching it in your user account. Also, you can try putting the graphics card driver into VGA mode.
Running in Vista SP2 compatiblity and as Admin allows the application to boot. Its pretty flaky and jammed up hard when the auto save kicked in. I openned SpeedGrade and it crashed too, so I uninstalled it and am planning to reinstall.
Running as Admin and emulating a previous version of windows is not a solution.
Hi, please go to the following location on your computer & check if there are any files in that location.
C:\Program Files (x86)\QuickTime\QTComponents
If there is any file in that folder, then please move the files out of that folder & try launching Premiere Pro again.
Also if you get any error message regarding the display drivers, then please check if you have the latest drivers.
You can get the drivers for your card from the following webpage http://www.nvidia.com/object/win8-win7-winvista-64bit-327.23-whql-driver.html.
Perform a clean installation of the drivers & reboot the system.
Check if you are able to lauch the application.
