  • Microsoft Windows 2000 Professional Edition

This article was previously published under Q252725


During the system files portion of Setup, when you perform one of the following operations:

  • Running the Windows 2000 Readiness Analyzer
  • Running Winnt32 /checkupgradeonly
  • Running Winnt32 and attempting to upgrade.

You may receive the following error message:

WINNT32 this program has performed an illegal operation.
WINNT32 caused an invalid page fault in module KERNEL32.DLL at 0167:bff88396

Stack dump:


This error message can occur if Quickbooks, Powerbuilder, Cabnetware, or Oracle for Windows 95 is installed on your computer.



To resolve this issue, locate the Qbconv32.dll file and rename it to Qbconv32.dl_. If you find multiple copies of this file on the computer, rename each copy.


To resolve this issue, locate the following files and rename them to a .dl_ extension. If you find multiple copies of these files on the computer, rename each copy:



To resolve this issue, locate the following files and rename them:

L323d.dll rename to - L323d.dl_
L32cutes.dll rename to - L32cutes.dl_
L32cutl.dll rename to - L32cutl.dl_
L32cwv.dll rename to - L32cwv.dl_
L32dlg2.dll rename to - L32dlg2.dl_
L32estmt.dll rename to - L32estmt.dl_
L32lay.dll rename to - L32lay.dl_
L32mxs.dll rename to - L32mxs.dl_

Oracle for Windows 95

To resolve this issue, locate the following files in the orawin95 folder (by default) and rename them:

NPL80.dll rename to - NPL80.dl_
NR80.dll rename to - NR80.dl_
NT80.dll rename to - NT80.dl_

If you find multiple copies of a file on the computer, rename each copy.


Microsoft has confirmed that this is a problem in Microsoft Windows 2000 Professional.


You may also find the offending entry at the end of the Setupact.log log file. The entry would look something like the following example:

Warning     Modules:Access violation while checking c:\Program 
            Files\Intuit\QuickBooks Pro 99\QBCONV32.dll

If you are upgrading, you must rename the .dl_ file back to .dll after the upgrade completes so the program can start working again. After the upgrade completes, you can safely rename the file. Or you can uninstall the offending program. This issue only happens while the readiness analyzer or Winnt32 is running inside Windows 95 or Windows 98. After you install Windows 2000, you can rename the file back. This does not cause any issues and the program functions normally again.

Another cause is a dynamic-link library (DLL) file that is included with Powerbuilder (Pbctlo50.dll). To resolve this issue, rename the file, let Setup continue, and after Setup or the Readiness Analyzer tool finishes, rename the file to its original name so that Powerbuilder works again.

Cabnetware (or Cabware) may also cause this problem. This is Cabinet Design Software. Uninstalling the program resolves the issue. The readiness analyzer has problems with the following files from Cabnetware:

  • L323d.dll
  • L32cutes.dll
  • L32cutl.dll
  • L32cwv.dll
  • L32dlg2.dll
  • L32estmt.dll
  • L32lay.dll
  • L32mxs.dll
