Please refer to the following forum thread on error code A12E5.
Hope this helps.
Please let me know in case of any problem.
What a worthless response!
Pointing me to a bunch of threads I alreay read and tried is NOT helpful. I have listed what I have tried in my original post, including unstallig the software, using Adobe cc cleaner, installing in safe mode, etc.
If you have a NEW suggestion, please let me know what it is.
