I have MS Project 2002 Prof application installed on a CITRIX server MetaFrame XP Version 1.0 SP3, FR3, and running on Windows 2000 server SP3. My users connect using an ICA session to the server desktop and launch the application, users OS is Windows XP Prof. I have noticed that only users with local administrative rights could start this application [MS Project 2002 Prof], all other users fail to launch the application and they receive the error. "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" I have noticed that when the users try to launch the application as if it trying to add more features and failing, since users do not have the right change the existing setup, so the application launch fail to start. I have inspected the current setup to find out if there is any missing components or features that are not installed, but find that the current installation to be full and complete. Note: The application act as a thick client to allow users to connect to another Enterprise Project Management server. Any help is appreciated. Abdul Abdo
