Here is an Premiere Elements 12 Error 1 story with a happy ending. Please check it out and see if any of it works for you with your Premiere Elements 11 problem. At this point, I do not think that product licensing has anything to do with your issue, but time will tell.
In the above link the user sought alternative installation files and that worked to resolve the issue as described in the link.
If you were to follow that approach, you could download Premiere Elements 11 tryout files from the following link and then insert your purchased Premiere Elements 11 serial number in it.
The above web site offers the tryouts of some earlier versions but does not sell them.
For this to work for you, you must read very carefully the Note: Very Important Instructions at that web site. Otherwise you will be greeted by Access Denied.
Please consider and then let us know the outcome.
Add On...I forgot to ask. Are you working from installation files purchased from Adobe or from a purchased installation disc that came with boxed packaging of the product? If the former, you could always get another download of the product at "My Orders" or "My Products" at Adobe.
Thank You for the info. Unfortunately, I haven't been able to solve the problem yet. I reinstalled Premiere Elements 9 and it is working fine. So, I'll use that until I figure out the Elements 11 problem.
Again, thanks for your response
Thanks for the follow up.
Did you have time to try the installation files from a difference source? Are you saying that you tried that and it did not work?
We will be watching for further developments when you get a chance.
