ID: Q156676

The information in this article applies to:

Microsoft Windows NT Workstation version 4.0
Microsoft Windows NT Server version 4.0

SYMPTOMS

If you attempt to install Microsoft Windows NT version 4.0 on a computer that uses a 80386 processor, the following error messages may occur:

Windows NT requires an 80486 or later processor. Setup cannot continue.

CAUSE

Microsoft Windows NT version 4.0 is compiled for use on computers with 80486 or later processors and will not install on a computer with an 80386 processor. Some computers on the Microsoft Windows NT version 3.5x Hardware Compatibility List (HCL) contain the 80386 processor. Although the HCL for Windows NT 4.0 suggests that computers on the Windows NT 3.51 HCL are expected to run Windows NT 4.0, any computers listed with the 80386 processor will not run Microsoft Windows NT 4.0.
