I have a customer actions setup to display a message to the user if they are running on a 32 bit operating system. I have this set as the 1st action in the UI Sequence. the problem I am having its always run no matter if its 64 or 32 bit. What am I doing wrong?
VersionNT64 will be undefined if the Template Summary value of your installer indicates a 32bit processor. This is because for compatibility reasons a 32bit installer can not run 64bit code.
So if you have a 32bit Template summary value, VersionNT64 will be undefined regardless of the bit type of the OS.
If you change the Template summary value to target a 64bit machine, then you will be unable to run the installer on a 32bit machine as windows won't allow this, and you will automatically receive a compatibility error, which may be a solution for what you are trying to achieve.
Currently our product works on both 32 and 64 bit OS. We are wanting to phase out 32 bit so I am trying to get the install to throw up a popup message if we detect a 32 bit and let them know we recommend they upgrade their machine to 64 bit. Is there another way to detect if we are on a 32 bit OS?
