OK, I am having troubles with msi apps.

How do you assign workstation rights to the msi? To the msi file, or to
the folder containing it?

I have tried assigning the rights to the ou containing the workstations,
should this work - don't the workstations inherit these permissions?

Should I put the workstations in a workstation group and assigh that
group rights?

When I browse to the network location of the msi, and right click to get
the properties for the msi app or its folder, only the users and user
groups show in the list to assign permissions, what tool do you use to
assign the workstations or workstation group permission to the location/app?
