WinNT 4.0 Upgrade CD Will Not Upgrade WinNT 4.0 Installation
This article was previously published under Q154538 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.
