I am running my Premiere Elements 8 on Windows 7 64 bit, latest Nvidia drivers.
The splash screen where you launch the actual program loads fine and my projects open from the OPEN PROJECT menu the first time, but if I close the program and try to once again open a project from the splash screen/launcher window it disappears and nothing happens! I must reboot to work on my project again. This happens if I try NEW PROJECT or OPEN PROJECT. Nothing is on my taskbar, but if I go to the task Manager in the processes I see Adobe Premiere Elements.exe *32 still running. Is there a 64 bit version?
Welcome to the forum.
There is no 64-bit version of PrE. Only PrPro CS5 (and the soon to be released CS5.5) is 64-bit.
As for the hang (and continued running), there might be something in this ARTICLE, that will help.
