MSI Problem

Hello

We have a problem with msi-installations that uses advertising-mode. MSI Packages have been installed as administrator without problems. As soon the user gets logged in and tries to start the application, the system revokes the request by the following error message:

Only administrators have permission to add, remove or configure server software during a Terminal services remote session. If you want to install or configure software on the server, contact your network administrator.

What other solution does exist than only disable the advertising mode when not supported by the os.
We want to use the normal selfrepair mechanism as well under the Terminal Servers.

Kind regards
Salvi
