Altiris 7.1 Detection Checks Working Incorrectly

Hello there,

I'm looking for clarification about detection checks.  For example, I'm deploying a  small application which may install on a 32 or 64 bit Windows 7 machine....

My detection check reads ....

-AND

      (File Path = "C:\Program FIles (x86)\Appname\App.exe")

               +OR

                    (File Path = "C:\Program Files\Appname\App.exe")

The installer is the same regardless but i need to check for the presence in both places.  This is similar to checking for a regkey @ HKLM\Software\APP OR HKLM\Software\WOW6432Node\APP.....I'm not sure what i'm doing wrong but the software fails the detection check every time.

Thank you,
