SYMPTOMS
When you attempt to reinstall the upgrade version of Microsoft Windows NT version 4.0 over an existing version of Microsoft Windows NT version 4.0, you may receive one of the following error messages:

- No previous version of Windows NT could be found on your computer. Setup is unable to verify that you qualify to use this upgrade product. Press F3 to exit.

- Setup could not find a previous version of Windows NT installed on your computer. To continue, Setup will need to verify that you qualify to use this upgrade product. Please insert your Windows NT Workstation CD- ROM from Windows NT 3.1, 3.5, or 3.51, into your CD-ROM drive.

- Setup could not find a previous version of Windows NT installed on your computer. To continue, Setup will need to verify that you qualify to use this upgrade product. Please insert your Windows NT Server CD-ROM from Windows NT 3.1, 3.5, or 3.51, into your CD-ROM drive.

If you insert a Windows NT CD-ROM from a previous version of Windows NT, you can install Windows NT version 4.0 to a new folder, but you cannot reinstall over the existing installation of Windows NT version 4.0.



CAUSE
The Windows NT version 4.0 Upgrade Setup checks for Microsoft Windows NT versions 3.1, 3.5, and 3.51. Setup does not recognize Windows NT version 4.0 as a version of Windows NT that can be upgraded.



RESOLUTION
To work around this behavior, upgrade using the full retail version of Microsoft Windows NT version 4.0.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Windows NT version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
