Acrobat Reader is present?

[ecu]

Amigos:
Many times you want to check if certain sw is installed in the users 
computer, this is true for Quicktime (in order to run QT files like 
QTVR etc), inthat case it is easily tetsted with the result of the 
function QTVersion(). But what if you want to know if Acrobat is 
installed?

I want to be able to read pdf files directly within RR in the Mac, I 
can use a player and QT 6.3  but the trick doesn't work with Windows,  
pdf files can be viewed with the Excelent AltBowser only if the machine 
has Acrobat.

Any ideas? I understand that, in the winboxes there is something like a 
"Registry" where the system store info about the residing apps.

Have a good day,

Javier
