I am using Premiere Elements 13 on a Windows 7 Professional PC. I do have an internet connection. I am being asked for activation on pretty much all of the export options for MPEG (this is what I primarily use). I obtain the code and it looks like it is installing but then the error code message appears and I get a "you do not have permission" message. Quicktime is up to date. Again, I have been using this program for months with no issues and now I am getting activation requests. Thanks for your time.
Thanks for the reply.

Adobe Premiere Elements 13
and, in the Adobe Premiere Elements 13 Folder, find and right click the file specifically named Adobe Premiere Elements.exe. Then double click this file to open to the Premiere Elements workspace where you proceed to your importing, editing, and exporting. Any improvement yet?
Also, look at the export situation with and without the Hardware Acceleration enabled in preferences. See Edit Menu/Preferences/General and the preference named "Use Hardware Acceleration (works on Intel HD Graphics 2000 and higher)".
Also, delete the Adobe Premiere Elements Prefs file found
