I have a smaller user base; I used this issue as justification to have Adobe Reader be the default PDF application and thus users only open Adobe Acrobat to edit or create PDFs. I�ve not yet automated my upgrades for Acrobat 6/7 Standard/Pro thus Reader is a safer default for the web and email attachments.

If you go the batch route I�d recommend something like the following example:

if not exist "C:\Location of Acrobat professional\Acrobat.exe" goto end
ftype acroexch.document="C:\Location of Acrobat professional\Acrobat.exe" "%%1"
:end

Note: the double percent signs before the variable (%%1) are required, or the batch file would interpret %1 as the first command line argument.

There are quite a few ftype entries for Acrobat Reader:
acrobat=C:\Program Files\Adobe\Reader 8.0\Reader\AcroRd32.exe /u "%1"
AcroExch.Document="C:\Program Files\Adobe\Reader 8.0\Reader\AcroRd32.exe" "%1"
AcroExch.Document.7="AcroRd32.exe" "%1"
AcroExch.FDFDoc="C:\Program Files\Adobe\Reader 8.0\Reader\AcroRd32.exe" "%1"
AcroExch.XDPDoc="C:\Program Files\Adobe\Reader 8.0\Reader\AcroRd32.exe" "%1"
AcroExch.XFDFDoc="C:\Program Files\Adobe\Reader 8.0\Reader\AcroRd32.exe" "%1"
EBXTransfer="C:\Program Files\Adobe\Reader 8.0\Reader\AcroRd32.exe" "%1"
EDNActivation="C:\Program Files\Adobe\Reader 8.0\Reader\AcroRd32.exe" "%1"

I recommend testing to see which of the above you need to change.
