Thank you John for the reply.
Unfortunately, only older versions are listed; not PE12
Find the link to download the current v12 trial and then activate with your serial number
I would definitely contact Adobe via its Adobe Chat to sort out the situation with your order and Adobe's record of it. You did purchase from Adobe direct? I am assuming yes.
What computer operating system did you download your Premiere Elements 12 to when you purchased it from Adobe?
For contact with Adobe's Chat, please click on...
Membership, Account, Payment
Payments, Invoices, Orders
The link is set to that location. If the link set does not hold, then you will need to navigate to the Chat Panel using the titles as guides.
At this moment, the Chat Panel is active and ready to be used.
However, for the immediate situation, you can download Premiere Elements 12 tryout files from the following web site. Be sure to read and carry out carefully (to the word) the Note: Very Important Instructions on the web page so that you do not get Access Denied. You can use the download and install as a tryout or insert your purchased serial number into the installation files to make it your working copy. Assure that you are selecting the correct files as replacements specific to what you purchased.
Any questions or need clarification, please do not hesitate to ask.
Thank you John, that did the trick.
