In Advanced Installer, how can I know if a 32bit process is running within a 64bit machine? I need to know this in order to prevent final users to install our application in given scenarios. Our approach is to use custom actions to detect if a given process is running, but it seems that Advanced installer isn't able to recognizes the ".exe *32" in the string end. Does someone know how to proceed in this situation?

This is not the correct approach. To stop users from installing the application on 64 bit machines you need to go to Launch Conditions page and uncheck all the 64-bit OS-es from the list. This will make your package to stop from installing on 64-bit machines.

Of course, for clients running a 64-bit OS you need to create a new setup package, that contains the 64-bit version of your application. For this package set the package type 64-bit AMD from Install Parameters page. Also, in Launch Conditions page make sure you uncheck all the 32-bit OS-es.

If you're really using a custom action to detect a particular 32-bit process, it's nothing to do with Advanced Installer. Your code enumerates the processes to find the one you want, does an OpenProcess() to get a handle and then calls IsWoW64Process, and closes the handle. If you have an x64 MSI file it won't install on a 32-bit system anyway, so I'm assuming that you are trying to prevent your x64 MSI file from installing on a 64-bit system if a certain 32-bit process is running.
