Under windows .msi installer, if you specify a custom action to be run at an application's installation time, it will get run under the "SYSTEM" user. Can I trick it by passing a command line parameter to the custom action (.exe file) and make it run under the currently logged on user?

Is this what you are looking for?

RUNAS

Execute a program under a different user account.

Syntax RUNAS [/profile] [/env] [/netonly] /user:user Program

Key /profile Option to load the user's profile (registry) /env Use current environment instead of user's. /netonly Use the credentials specified only for remote connections. /user Username in form USER@DOMAIN or DOMAIN\USER (USER@DOMAIN is not compatible with /netonly) Program The command to execute

Enter the password when prompted.

When you start a program with RunAs /netonly, the program will execute on your local computer as the user you are currently logged on as, but any connections to other computers on the network will be made using the user account specified.

Without /netonly everything will run under the user account specified.

I believe 'runas' is a shell command. I need the command to be 'myexe.exe' followed by some argument which would make it run under different credentials. Any other hints ? – kellogs Jan 13 '11 at 20:20

Any modifier that comes after the command has to be built into the program. An example is iexplore.exe /k This opens Internet Explorer in kiosk mode and is built into the executable. Unless you write a script which executes the shell command with the program if you pass a modifier to the script like myscript.bat that runs myfile.exe normally but myscript.bat /another that runs myfile.exe through the shell command as another user. – Stanley Williams Jan 13 '11 at 20:25
