Setup Fails to Upgrade Over Existing WFWG Installation (90201)
The information in this article applies to:
- Microsoft Windows for Workgroups 3.1
This article was previously published under Q90201 SYMPTOMS
Windows for Workgroups version 3.1 Setup may fail to upgrade an
existing installation of Windows for Workgroups even if the minimum
disk space requirement of 500 kilobytes (K) is present. Setup operates
normally until it reaches the file WIN386.EXE. You then see a dialog
box telling you there is not enough disk space to perform a complete
upgrade.
You will only notice this problem if you have between 500K and 545K of
free disk space on the drive of your current Windows for Workgroups
installation.
CAUSE
Usually, Windows for Workgroups Setup checks to make sure that at
least 500K of disk space is available. Usually there is slightly more
than this amount available, resulting in no problems when you perform
an upgrade over Windows for Workgroups.
Setup uses the Windows dynamic link library (DLL) VER.DLL, which
copies files and verifies Windows component versions. To function
correctly, VER.DLL requires as much disk space as the file it is
copying. When it reaches WIN386.EXE, it cannot find enough space and
stops the installation.
STATUS
Microsoft has confirmed this to be a problem in Windows for Workgroups
Setup version 3.1. This problem does not occur in later versions of Windows
for Workgroups.
