I need to get an msi installed on a number of machines. I've written a script to check the version and deploy if necessary, but it doesn't seem to like the msiexec call. Can msiexec be run from a limited user, or only administrators? Can someone point me in the right direction.

Alternatively, what's a better solution?

You need the "Always install with elevated privileges" setting in Group Policy, either as a Domain Policy if you have AD, otherwise as a local policy on the individual PCs themselves.

Find it in User Configuration\Administrative Templates\Windows Components\Windows Installer.

So, that affects all uses of MSIEXEC? I've got a VBS that runs on startup and installs an MSI that lives on a server (if the MSI has a higher version). Could you please confirm? – Tim Almond Oct 26 '09 at 18:04
@Tim: If it's running at startup (not login) the script is running w/ system level permissions. – Zypher Jan 29 '10 at 2:18
