You realize that you are not using Premiere Elements 12/12.1 optimally on Windows Vista be it 32 or 64 bit. You still have a Premiere Elements 12/12.1 32 bit application which has computer resource issues when trying to get a larger project taken to completion successfully. With the 32 bit system, the maximum supported installed RAM = 4 GB, typically with 3.2 to 3.0 GB or less of that available. And, you appear to have only 3 GB RAM to start with.
It sounds like it may have worked before from what you wrote. How long ago did it work? And, what was your last activity in a project before you could no longer get the program to open. Are working with a home computer or is this computer part of a company network? In your present computer environment moving to Premiere Elements 13 is not a choice since Premiere Elements 13 does not support Windows Vista 32 or 64 bit.
You could go through the usual drill
a. Latest version of QuickTime installed on your computer with Premiere Elements 12/12.1?
b. Running program from a User Account with Administrative Privileges?
c. Video card/graphics card up to date according to web site of the manufacturer of the card?
d. Does problem exist with and without the antivirus and firewall(s) disabled?
e. Where do you have the Scratch Disks directed and how much free hard drive space is at that location?
f. Did you install the program to the default location on the Local Disk C?
What was your way of getting the program to work previously when problems developed?
Let us consider the above and then we can decide what next.
Thank you.
