Unassociated Desktop App Hijacked by Creative Cloud
I purchased Adobe Acrobat Pro, Student and Teacher Edition (2017) from a third party vendor as a gift for my qualifying partner so that she would be able to work from home. I was provided with a download link and a serial number and I downloaded and installed the program with no problem. The first time she used the program, it logged in and linked to my Creative Cloud Photography account and after a five day trial reverted to the stripped down free version of Acrobat. I have attempted several times to resolve this problem through Adobe's customer service to no avail.
What do I need to do to separate the stand-alone / non-subscription version of Acrobat Pro from my CC Photo account so that my friend can use the full-featured program?
