Summary: Acrobat Pro 7 installer fails to detect other Acrobat
                    Pro installations
           Product: Wine
           Version: 1.0-rc1
          Platform: All
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement

In wine it is possible to install multiple versions of Acrobat Pro without
complaint. Specifically, I have been able to install both Acrobat Pro 6 and the
tryout version of Acrobat Pro 7.

However, when I tried to do the same in Windows, that is when I tried to
install Acrobat Pro 7 (Tryout Version) when Acrobat Pro 6 was already
installed, I received the following error message:

Setup has detected that you already have a more functional product installed.
  Setup will now terminate.

Question: is it the wine team's desire to implement Windows completely, both
good and bad? Or merely to implement the good bits and leave the bad?
