The system account is irrelevant here. What matters is the list of rights that the msiexec process is running with, and it does not have all possible rights enabled all of the time. I think you've already discovered that, so I don't know what to advise. I forget where this is documented, but that code (and therefore your custom action) is running with a limited list of rights (something that started on MSI 4.0) that does not include the one required to terminate processes.

Subject: Re: [WiX-users] Running a custom action with elevated privileges Umesh, Thanks for responding to my question. I am using OpenProcess(PROCESS_TERMINATE, ...). When I execute the same exact code from a system account with elevated privileges using PSEXEC, it works, so I know there is something wrong with the privileges when my code runs as a Custom Action. I also have verified this by looking at the privileges with Process Explorer. Any other ideas?
