Premiere Elements 12 on Window 7 64 bit. What video card/graphics card does your computer use - AMD Radeon?
I have found this YouTube video on the subject of Error 126 with details for resolving the problem.
The link was contributed in an old 2013 thread here by the ID danneomarre (see post 6 of the following thread)
Please let us know if that worked for you.
Add On...When all is OK and working, please update 12 to 12.1 Update using an opened project's Help Menu/Update.
Thanks, it seems to work with "copy atio6axx.dll atiogl64.dll" copied in CMD (run as admin)
I'll test more tomorrow
Best regards, Jürgen
Thank for the very great news "it seems to work". Great job in sorting through the troubleshooting.
Hope the news is also good tomorrow.
Please let us know the outcome when you have the time. This type of problem is not reported here that often so it is good to gather
as much information about it as possible.
Your follow up is appreciated by all.
