a typical command in the console would then be:
msiexec.exe /i "PATH" TRANSFORMS="PATH" ALLUSERS=2 /qb

to uninstall we would use this in the Uninstall tab:
msiexec.exe /x{GUID} /qn

however to do a reinstall you would need the following commands and from my testing if you reinstall from the console of an MSI these commands dont get implemented just whatever you had in the original command.
msiexec.exe /fa "PATH"

Any way we could change something in the database that says if the task is a command use "This" if reinstall is selected?

Thanks,
Mike 

msiexec.exe /fa "PATH"

Then assign that task to the computers needing to have the application reinstalled.

We'll enter a feature request that Command Task properties should have another tab for "reinstall." Thanks for the clearly-stated example!
