I accidentally installed an upgrade of Adobe Acrobat Pro 7 to Adobe Acrobat Pro 11.
(I had the Adobe Pro 7 for Windows and was sold the upgrade without being told that I had to separately buy the base version for Mac)
To be clear : I don't have Adobe 7 on my Mac but ran the upgrade to Adobe Acrobat Pro 11.
I get the error
The serial number you provided is valid, but a qualifying product could not be found on this computer.
This of course makes sense.
I then tried to install the Trial version of Mac Adobe Acrobat Pro 11, but when I go to start that program, I get the same message.
I want to remove the 'upgrade' info on the Mac so that when I run the trial version, I don't get that error message.
How do I do that?

I solved it.
I moved the /Library/Application Support/Adobe/Slcache and Slstore into a backups folder.
Then I ran the installer again.
Running the uninstaller did not remove these files before - that's why we kept getting the error.
