How do I check whether Adobe Acrobat is installed using WiX?

The whole question is pretty muc开发者_开发问答h in the title.

Acrobat Reader, Pro, Standard, 3D, etc? What version? Do you need Acrobat specifically? A PDF editor? A PDF viewer?

If you're not picky and are just looking for Acrobat Reader/Pro/Std, I'd start with the HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AcroExch.Document registry key.

If you're only concerned with a PDF application in general (Adobe, Foxit, Nitro PDF, etc, etc) then start with the HKCR\.pdf registry key.
