That is OFTEN caused by a Windows DLL change that renders your graphics adapter driver out of date
•What is your exact brand/model graphics adapter (ATI or nVidia or ???)
•What is your exact graphics adapter driver version?
•Have you gone to the vendor web site to check for a newer driver?
•For Windows, do NOT rely on Windows Update to have current driver information
•-you need to go direct to the vendor web site and check updates for yourself
•ATI Driver Autodetect http://support.amd.com/en-us/download/auto-detect-tool
•nVidia Driver Downloads http://www.nvidia.com/Download/index.aspx?lang=en-us
Dual video problems - Do you have dual graphics adapters?
Go to the Windows Control Panel and select Hardware and Sound and then select Device Manager... In Device manager you click the + sign to the left of Display Adapters... and see if 2 are listed
IF YES, read below

Did you do the update of Windows 8.1 64 bit on a computer that already had Premiere Elements 12 installed in a prior Windows operating system on the same computer? Or did you buy a new computer with Windows 8.1 64 bit and do a fresh install of Premiere Elements 12 on it? I suspect the first case.
But, before all, just assure that the problem exists with and without the antivirus and firewall(s) disabled.
If this is the first case, then I would uninstall Premiere Elements 12 and QuickTime, do a free ccleaner run through (regular cleaner and registry cleaner parts), and then do a reinstall with antivirus and firewall(s) disabled.
Please let me know if I have interpreted your question and its background correctly.
We will be watching for further developments so that we can decide what next.
Graphics Adapter/Driver - Intel HD Graphics 4600
Went to both Intel and Toshiba websites- downloaded, installed graphics driver.
NO CHANGE - PE-12 crashes at launch
NOT running dual monitors.
PE-12 will crash at launch- this happened after installing latest Windows 8.1 updates in the past few days.9/14-17/14
Thanks for the reply which was a clarification for us.
I thought that you had updated from another computer operating system (like 8) to 8.1. I did not interpret that you were referring to
Windows Updates for the one and only Windows 8.1 64 bit.
Since this is the case, have you tried to remove the Windows Updates whose install seems to coincide with the Premiere Elements 12 issue
to determine if that can get you back to the Premiere Elements 12/12.1 on Windows 8.1 64 bit working condition? I have Premiere
Elements 12/12.1 on Windows 8.1 64 bit and have all the latest Windows Updates and am not have any problems with Premiere Elements
12/12.1. So, right not those Windows Updates are not my prime target, but should be looked at nonetheless.
Have you considered a System Restore?
Please review and then we can consider what next if the above does not have any impact on your issue.
Add On...As a point of reference, the video card/graphics card used by my Windows 8.1 64 bit is Intel HD Graphics dated 1/29/2014,
version shown as 126.96.36.19947.
>NOT running dual monitors
What I said, and the links I posted, were not about dual MONITORS, but about dual graphics adapters... such as an Intel chip on the motherboard and then a separate ATI-or-nVidia card... which is a situation that often causes problems
unistalled recent Windows 8.1 updates...PE-12 still crashed at startup. Found .prf file; deleted it and viola! PE-12 starts up and operates as normal. Just a coincidence that Windows 8.1 updates had recently been installed. Should have gone for the easy fix right from the start.
Great news, great job.
What did you delete, the Elements Organizer 12 Settings file (psa.prf)?
The Premiere Elements 12 Editor also has a Settings file named Adobe Premiere Elements Prefs file, and, if that does not work for an Editor suspected problem, then you delete the whole 12.0 Folder in which the Adobe Premiere Elements Prefs file exists. Need to have Folder Option Show Hidden Files, Folders, and Drives active so that you can see the complete path.
For the benefit of those reading your thread, the path to these Settings files for Premiere Elements 12/12.1 on Windows 7, 8, or 8.1 64 bit....
Premiere Elements Editor 12/12.1/Adobe Premiere Elements Prefs
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.
Elements Organizer 12/12.1/psa.prf
Local Disk C
and in the Organizer Folder is the psa.prf file that you delete or rename from psa.prf to psa.prfOLD.
