IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs.

Terminal Server uses a special installation mode for installing applications for multi-user use. This mode is activated by installing an application through the Control Panel Add/Remove Programs tool or by using the command "Change User /Install" at a prompt. If you use this command, you should return to normal execution mode by using the command "Change User /Execute" after installing the application.
Do not run the system in install mode (except to install applications). This disables user registry and .INI file mappings, which means each user running an application would share the same .INI file or registry entry, instead of having them on a per-user basis. The Terminal Server computer should always be run in execute mode.
If you have an application that runs only in install mode, the application is probably looking for a file in the SystemRoot directory rather than the user's Windows directory. You can modify the Terminal Server registry so that the system will allow the application to use the SystemRoot as its Windows directory. To do this, perform the following steps:
WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.
For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it.
