I want to do the following:
1- Use the UAC plugin so that the installer can be run as an admin and still be able to start the application as the logged on user
2- Detect if the application is already running so I can tell the user to close it. I am using the FindProcess for this purpose (http://nsis.sourceforge.net/FindProcess
The process calling FindProcess is running as Administrator. The script needs to get a handle on the first module of each process in order to call GetModuleBaseName. This is done through a call to OpenProcess().
However, a given user (even Administrator) cannot open the process of another user. The OpenProcess call always return Access Denied.
I see that I should grant SeDebugPrivileges to the installer process, but this just seems so overkill. Heck I just want to see if some .exe file is running or not.
Any clues to help me?
