PRB: Unattended Setup Does Not Honor Win31Upgrade=no In Answer (163615)


The information in this article applies to:

  • Microsoft Windows NT Workstation 4.0
  • Microsoft Windows NT Server 4.0
This article was previously published under Q163615

SYMPTOMS

You want to run Unattended Setup on a computer that already has Windows 3.x installed. But because you do not want to upgrade Windows, you specify "Win31Upgrade=no" in your unattended answer file.

Even though you do this, there is a message during text mode setup saying:
Setup has found a previous version of Microsoft Windows on your hard disk in the directory shown below.

C:\WINDOWS

Setup recommends installing Microsoft Windows NT in the same directory.

CAUSE

When Setup finds Windows, it first checks if there is enough free space on the partition containing Windows before it asks for the upgrade. If there is insufficient space, Windows NT Setup displays the message above before honoring the setting in the unattended answer file.

The drive is too full to hold Windows NT, which requires approximately 122 MB (1 MB = 1,048,576 bytes) of free disk space.

STATUS

Microsoft has confirmed this to be a problem in the 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.
