Check if application is already installed

[Guest Jan Habraken]

My cd-roms start automatically with an AutoIt script.

Some of the file on the cd-rom are Acrobat PDF's and I want to advice the user to download the Acrobat Reader is it is not already on the PC.

How can I let AutoIt check if Acrobat Reader is already installed?

Thank's for all good suggestions.

Jan

RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\Acrobat Reader","")
if @error then
