256986 Description of the Microsoft Windows Registry
When you attempt to start Outlook for the first time after installing Microsoft Office 2000, you receive the following error message even though you are logged on as the administrator, or as a member of the local Administrator group, on the Microsoft Windows NT 4.0 Workstation computer:
Cannot start Microsoft Outlook. Outlook could not be configured, because Administrator privileges are required for you to install some types of software on this computer. Before you can use Outlook, you must either log on to your computer as an Administrator and finish configuring Outlook, or ask your System Administrator to configure Outlook e-mail support for you."
You do not have sufficient permissions on the following registry key:
Change the permissions on the registry key to Full Control.
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 set the permissions to Full Control, follow these steps:
  1. Log on as the local administrator or member of the Administrator group.
  2. On the Start menu, click Run. In the Open box, type Regedt32 to run the Registry Editor. Click OK. Regedt32.exe must be used, rather than Regedit.exe, to make Security changes.
  3. On the Window menu, click HKEY_LOCAL_MACHINE on Local Machine.
  4. Navigate to the following registry key:
  5. On the Security menu, click Permissions.
  6. Click the <computer name>\Administrators group, and on the Type of Access list, click to select Full Control (where <computer name> is the computer you are logged on to).
  7. Click OK, and on the Registry menu, click Exit.
  8. Restart Outlook. The first-run portion of Setup for Outlook will complete without further error.
Making this security change while logged in as administrator will also affect any user who is a member of the Administrator group.
