Summary: Adobe Acrobat Pro 7 Tryout installer crashes while
                    trying to remove printer
           Product: Wine

            Status: NEW
          Keywords: download, Installer
          Severity: normal

The best place I could find so far to download the tryout version is
http://www.winsoft.eu/support/download-adobe-acrobat.php
This points to ftp3.winsoft.fr, which I think is a safe and reputable site.
The tryouts there are all in Eastern European or Middle East languages,
but the installers let you pick English.

Running the e.g. greek installer for Acrobat Pro 7 tryout,
the first issue is an apparant lockup, but that's just 
the installer taking five seconds loading each of ten EULAs.
The first serious problem is a crash when it tries to remove 
the old distiller printer.  Here's the intersting part of the +msi,+winspool
log:

This might be a bug in our winspool, but I'm flagging it as
msi because I'm not quite sure.  (And getting a +relay is going
to be painful unless you can turn on +relay just before the
custom action is run.)
