Adobe Reader Installed Check

I feel like such a dweeb, this seems like a simple question, but I've been having trouble with it--how can I check if Adobe Acrobat Reader (You know, for PDFs) is installed? 🤪

EnumRegKey $0 "HKLM" "SOFTWARE\\Adobe\\Acrobat Reader" "0"
IfErrors 0 EndError
  # Put anything here to be executed when the code above
  # has an error
EndError:
StrCmp $0 "" 0 EndNotExists
  # Put anything here to be executed when Adobe Acrobat
  # doesn't exist
EndNotExists:
# Normal Code 

This code detects too its major version (returned on the result).

(Tested only with Acrobat Reader 6.0)
