An executable will always be executed as a child process of the process which launches it. Even if you ship a DLL as your custom action you'll need to call RunDLL32.exe to actually execute the code.
I don't think this is the question you need to be asking. What are you actually trying to achieve with this? My guess is you have UAC/elevation issues with your custom action.

If I run an exe in an msi through some custom action,it is run as an out of process method. That is to say the msiexec runs as process1 and the exe runs as process2. Would it be possible to somehow run the exe within the same process as msiexec ie process1 and process2 as one process? ------------------------------------------------------------------------------ Don't Limit Your Business.
