SYMPTOMS
When you attempt to run the Organization Chart Wizard in Microsoft Visio, you may receive the following error message:

Unable to register ISAM C:\Winnt\System32\Msrd2x40.dll



CAUSE
This behavior can occur if you are using Microsoft Windows NT Workstation version 4.0, and you do not have appropriate permissions on the Microsoft Jet registry key.



RESOLUTION
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 avoid receiving this error message, you (or other users who log on to this computer) must have Full Control permissions on the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0

To avoid receiving similar error messages in Windows NT, the Everyone group must have the following Special Access permissions for the registry:

To set these permissions in Windows NT 4.0, follow these steps:  Click Start, and then click Run. In the Open box, type Regedt32, and then click OK. In Registry Editor, locate the following key by double-clicking the appropriate folders:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Jet\4.0

Click the 4.0 key, and then click Permissions on the Security menu. If Everyone is not in the list, click Add, type \Everyone, and then click OK. Click to select the Replace Permissions on Existing Subkeys check box. Double-click Everyone, and then click to select the following permissions:
