I have a script to install an .msi file out to a list of remote workstations. Works fine going out to XP machines. I now get error code 1603 when trying to run out to Windows 7 machines.

psexec -u "domain\username" -p "password" @\\domain\path\ComputerList.txt  msiexec /i "\\domain\path\InstallFile.msi" /passive /qn

Is it a permissions error? The user (me) is an Administrator on the Windows 7 workstations.

Any chance it would be an UAC setting blocking you? Can you try turning off UAC on windows client ? It will require a reboot : Here 2 method :… – Levesquejfrancois Dec 12 '11 at 18:09

Try using the -h switch for psexec. From the psexec help:

If the target system is Vista or higher, has the process run with the account's elevated token, if available.

This may resolve any issues that are occuring with UAC.
