256986 Description of the Microsoft Windows Registry


A component, including COMTI component libraries, can be installed in an MTS server package and the package can be exported to a remote Windows NT computer so the client application can run on the remote computer using DCOM.

The export process produces an executable file to be run on the remote computer for setting up registry entries (for example, ProgID, CLSID, and so on) for directing the remote client application to the component on the server where it runs under the control of Microsoft Transaction Server (MTS). Implementing the client application on the remote computer simply involves running the executable file on that computer. At that time, additional registry entries are provided for the future removal of this client application through the Add/Remove Programs utility in Control Panel. However, under certain conditions, the application's entry is missing from the Add/Remove Programs Properties dialog box under the Install/Uninstall tab.

The list entry is specified in the following registry value:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\CLSID\DisplayName



where CLSID is the CLSID of the remote application that is installed by running the executable file mentioned above.

If the value of DisplayName is more than 63 characters, the name doesn't display in Add/Remove Programs.

There is a workaround when this situation occurs. Edit the registry to change the value of DisplayName to a string less than 64 bytes in length. Then the revised name will appear in Add/Remove Programs list, and the application can be removed as desired.

MORE INFORMATION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To change the registry value, proceed as follows:
  1. Start Registry Editor (Regedt32.exe).
  2. Locate the DisplayName value under the following key in the registry:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\CLSID

  3. On the Edit menu, double-click DisplayName, type in a name no more than 63 characters long, and then click OK.
  4. Quit Registry Editor.
