Installing the Outlook\Word Add-In on Terminal Server
Terminal Server is a Windows environment in which users can make a connection to a central server and access Outlook on that server instead of their desktops.
To install the Outlook\Word Add-in on a Terminal Server
Before installing the Add-In on a Terminal Server, ensure that no one logged into the server is currently using Outlook\Word. Outlook\Word cannot be open during the Add-in installation.
To ensure that the Add-In is installed correctly to work in a multiple user environment, you must put the Terminal Server into a special installation mode before you begin the installation. You can put the Terminal Server into this special installation mode by using one of the following:
Install Application on Terminal Server tool under Programs in the Control Panel. This tool will run a wizard to help install the application.
Change user /install command at a command prompt. You will have to start the installation of the application manually.
After the application is installed, you must put the Terminal Server into execution mode before remote users can begin using the application. The Install Application on Terminal Server tool will automatically put the Terminal Server into execution mode when it is finished running. To put the Terminal Server into execution mode from a command prompt, use the change user /execute command.
For further instructions for putting Terminal Services in special modes, refer to the Microsoft TechNet article, Install Programs on a Terminal Server.
- Users must install the Add-In under their own profiles.
When installing the Add-In, users who are not administrators on the Terminal Server may see an error that says policies are set to prevent this installation.
To work around this error, you can add a registry value under HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\.
To add a registry value prevent this error
Locate or create the registry key HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\Installer.
Right-click Installer, then click New > DWORD Value.
Name the value DisableMSI.
Right-click DisableMSI, then click Modify and ensure the Value data is 0. (For more information about this registry value, refer to the MSDN article DisableMSI.)
