SUMMARY

This article describes how to clean up a COM+ catalog if the COM+ catalog becomes damaged.

MORE INFORMATION

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
To clean up a damaged COM+ catalog, follow these steps:
  1. Rename the %WinDir%\System32\Clbcatq.dll file to %WinDir%\System32\~Clbcatq.dll. Make sure that you include the tilde (~) at the start of the file name.
  2. Restart the computer.
  3. Start Registry Editor (Regedt32.exe).
  4. Locate and delete the following key in the registry:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\COM3

  5. At a command prompt, type cd %windir%, and then press ENTER.
  6. At a command prompt, type rmdir /s Registration, and then press ENTER. This is the location folder of the registration database.

    Note If you have MS04-012 installed, you must now re-install MS04-012. For more information about security update MS04-012, click the following article number to view the article in the Microsoft Knowledge Base:

    828741 MS04-012: Cumulative Update for Microsoft RPC/DCOM

  7. Click the Start button, point to Settings, and then click Control Panel.
  8. Double-click Add/Remove Programs, and then click Add/Remove Windows Components.
  9. Click Next to go through the reinstallation process, to reinstall COM+.
  10. If IIS is installed on the computer, IIS creates several COM+ applications. These applications will now be missing. To re-create these applications, run the following command at a command prompt:

    rundll32 %windir%\system32\inetsrv\wamreg.dll, CreateIISPackage

If Windows File Protection blocks the renaming and deletion, restart the computer in Safe mode, and follow these steps again.
