Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base: To fix this problem, you must make the changes to the registry.

• These steps work only for Flight Simulator X, Streets & Trips 2009, and MapPoint 2009. Do not follow these steps if this problem occurs when you use a different product.
• The HKEY_CURRENT_USER subtree in the registry contains the user profile for the user who is currently logged on to the computer. Because these steps include changing registry subkeys in the HKEY_CURRENT_USER subtree, you must change these registry subkeys for each person who uses the computer.
• You may have to reinstall Microsoft Office after you complete these steps.

To make the changes to the registry, follow these steps:

1. Log on to the computer that is experiencing the problem.
2. Exit all programs.
3. Start Registry Editor. To do this, click Start, click Run, type regedit in the Open box and then click OK.
   
   Note If you are prompted for an administrator password or for confirmation, type the password or provide confirmation.
4. Locate and then click the following registry subkey:
   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{4D36E967-E325-11CE-BFC1-08002BE10318}\Upperfilters
5. On the Edit menu, click Modify.
6. In the Value data box, type PartMgr, and then click OK.
7. On the File menu, click Exit to exit Registry Editor.
