OFF97: "Accwiz.dll Unable to Register Itself" Err on Windows NT

• Microsoft Office version 97 Professional Edition for Windows

SYMPTOMS

Moderate: Requires basic macro, coding, and interoperability skills.

If you install Microsoft Office 97 Professional Edition on a Windows NT Workstation, and then log on to the same computer as a different user and install Office 97 again, the installation maintenance screen appears. When you click Reinstall, the Setup program copies files; however after you receive the message that Setup is updating your system, you receive the following error:

   Accwiz.dll was unable to register itself in the system registry.

   Microsoft Office 97 Setup was not completed successfully.

CAUSE

This problem occurs when both of the following conditions are true:

• You have installed Microsoft Office 97 Professional Edition on a computer running Microsoft Windows NT 3.51 or 4.0 after logging on as a user who is a member of the Users group, but who is not a member of the Administrators group.
• You are reinstalling Microsoft Office 97 on the same computer after logging on as a different user who is a member of the Users group, but who is not a member of the Administrators group.

RESOLUTION

If you want more than one user to run Office 97 Professional on a Windows NT 4.0 Workstation computer, a member of the Administrators group should install it first. This allows different users to run Office programs without having to run Setup.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Office 97 Professional Edition. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
