I have an installation that can be run on Windows 2000 by a Standard User with Elevated Privileges. I have found a strange effect when testing it:

when installed, it can be uninstalled from the Add/Remove section of the Control Panel. It can also be removed by running setup.exe when the installation files are present on a local drive. However, when setup.exe is run from a removal disc in the CD drive, an error message turns up: "The administrator has set policies to prevent this installation".

How can I prevent this error occurring with a removal disc? One idea I have had is to put a Packaged version on the disc, so that whenever it is run it copies the installation to a local drive first and runs it there. That removes the problem. But why does it happen anyway?

By default, Windows Installer doesn't allow a restricted user to run the setup for an already installed product from a removable media for security reasons (the .msi file could be hacked). You can change this by seting the AllowLockdownMedia policy.
