What is your "Elements 12" that is not working? Is it Premiere Elements 12 or Photoshop Elements 12, running on Windows 7 64 bit?
It's premier elements 12. I have manually updated all windows, nvidia and adobe updates. It stops on the startup window if I try to use the video editor but will open the organizer tab and run that ok. The program had been running fine until last week.
When a program is working and suddenly stops, it is usually an indication that you have not fully updated and tuned your system.
Thanks for the follow up information for your issue regarding Premiere Elements 12 on Windows 7 64 bit.
Please check out two possible approaches to resolving the issue that you describe

Please review and consider the two how to suggestions in my blog post....I would try the second approach first (the one where you rename the SLStore Folder and SLCache Folder.
Also, you could check out Computer/Manage/Event Viewer/Windows Logs/Applications to look for information/error messages that may relate to the problem.
You could delete the Adobe Premiere Elements Prefs file. In Windows 7 64 bit, it can be found in the path
Local Disk C
and in the 12.0 Folder is the Adobe Premiere Elements Prefs file that you delete. If that does not work, then delete the whole 12.0 Folder in which the Adobe Premiere Elements Prefs file exists. Be sure to be working with Folder Option Show Hidden Files, Folders, and Drives active so that you can see the complete path.
Please let us know your results.
