 Last reviewed: February 24, 1995
Article ID: Q124360
The information in this article applies to:
  • Microsoft Windows NT Workstation version 3.5
  • Microsoft Windows NT Server version 3.5

SYMPTOMS

When you install Windows NT version 3.5 from a Mitsumi IDE CD-ROM the following error message appears: 

   Non Critical Error
   Error unable to open file IR32_32.DLL
If you choose Continue Setup, Setup completes normally.

CAUSE

This error message appears due to an incompatibility between the Mitsumi IDE CD-ROM and the Windows NT version 3.5 ATAPI.SYS driver.

WORKAROUND

To work around this problem, copy IR32_32.DLL (an Indeo codec [compression/decompression] file used with multi-media video) from the \I386 directory of the Windows NT version 3.5 CD to the \%SYSTEMROOT%\SYSTEM32 directory after Windows NT version 3.5 is installed.

STATUS
