Installed Xl Pro but get message Serial Number you provided is valid, but a qualifying product could not be found on this computer
I just bought and installed Adobe Acrobat XI Pro, but when I open it, or access a PDF file, I get the error message "Serial Number you provided is valid, but a qualifying product could not be found on this computer."
The list of products on the drop down list that comes with this message includes Adobe Acrobat XI Standard and Adobe Acrobat X Pro Macintosh, but doesn't include Adobe Pro XI for Windows. Selecting either of those, and using my serial number, fails, of course. As a result, I can't run my newly purchased program, or access any PDFs.
Please tell me what to do.
