Did you purchase PrE via a download, or on physical media?
If via download, was there only one installation file at that link?
Did you purchase discs or a download? If discs, I’d expect there is a 64-bit setup elsewhere on the discs. If a download, I’m not sure.
If you have Premiere Elements 12 on Windows 7, 8, or 8.1 64 bit or Mac 64 bit processor, Premiere Elements is a 64 bit application running in that 64 bit system.
You can verify that with a free program such as Process Explorer Sysinternals and its Image Type Field.
If you have an installation disc, I suspect you would not be getting into this situation.
I am suspecting that you have installation files from an Adobe download. If that is the case, did you have to select the download type? If so, could you have selected the wrong one? If you have installation files from Adobe, can you download the files again from Adobe from your Account/Order there?
You could also download Premiere Elements 12 tryout files (64 bit type) from the following web site and then insert your purchased serial number during installation of these files.
It is critical that you read carefully the Note: Very Important Instructions write up at that web site so that you do not get an Access Denied message.
Please review and then let us know the outcome.
Thank you all for your responses. I am using a download version of the program. Had downloaded it in Windows XP and saved the files on DVD. Apparently the downloader sends the variant of the software appropriate for the operating system. After switching to 64-bit Windows 7 the reinstallation from my DVD failed as described. Now I downloaded the trial version and entered registration number of the original purchase. Bingo! I'm back in business.
Thanks for the follow up with the great news "..I'm back in business. Good job.
Please do not hesitate to ask questions. We are glad for the opportunity to be of assistance.
Add On...Just a clarification asked...by registration number of the original purchase, you mean serial number?
