Adobe is not going to swap 13 for 12. It is selling only 13 download as you found out. So, you are going to have to purchase 12 if you want to use that program. It may still be available at some retail locations, such as Amazon.
If you are within 30 days of purchase and have purchase the download from Adobe, then contact Adobe via its Adobe Chat to get a refund. To do that, click on the following link
Membership, Account, Payment
Payments, Invoices, Orders
If the link does not hold its set, then you will need to navigate to Chat Panel using the above titles as guides.
Please let us know if you are OK with the above. If any questions or need clarification, please do not hesitate to ask. Reminder..we are not Adobe. This is a user to user
forum with an undefined frequency of an Adobe presence in it.
Have you read the Adobe document relating to workaround for the Premiere Elements 13 no DV HDV capture?
Please review and consider.
Thank for the reply. Glad that you found the suggestions useful.
We hope that all turns out well for you.
