Description of the Microsoft Windows Registry
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.
The following steps illustrate how to give the current user appropriate permissions to complete the MDAC installation successfully:
- Start the Registry Editor (Regedt32.exe).
- Locate and select the following key in the registry:
HKEY_CLASSES_ROOT\Interface
- On the Security menu, click Permissions.
- Give the current user (or a group to which the user belongs) Full Control permissions on this key. In Windows NT 4.0, make sure that you select the Replace Permissions on Existing Subkeys checkbox. In Windows 2000, make sure that you select the Allow inheritable permissions from parent to propagate to this object checkbox. Click OK to save your changes.
- Quit the Registry Editor.
After you make the changes, you can begin the MDAC installation.
