TITLE   :PRB: Read-only Msvbvm50.dll Causes Errors During VB5 App Install
PRODUCT :Microsoft Visual Basic for Windows
PROD/VER:WINDOWS:5.0
OPER/SYS:WINDOWS
KEYWORDS:

======================================================================
---------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Visual Basic Professional and Enterprise Editions for
   Windows, version 5.0
---------------------------------------------------------------------

SYMPTOMS
========

When trying to setup a Visual Basic 5.0 application onto a server that has
the Windows NT 4.0 Option Pack installed, the application setup may fail
with following error:

   Failure to register dll. 0x8000ffff

CAUSE
=====

The Windows NT 4.0 Option Pack set the Read-only attribute of the
MSVBVM50.dll file to True.

RESOLUTION
==========

To solve this problem, remove the Read-only attribute from MSVBVM50.dll on
the server.

STATUS
======

Microsoft is researching this problem and will post new information here in
the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION
================

Some users have been unable to install their Visual Basic 5.0 applications
because there was already a copy of Msvbvm50.dll on the system, and its
file attributes were set to Read-only. This problem is caused during
Windows NT 4.0 Option Pack Installation.

The following information from the Microsoft Windows NT 4.0 Option Pack
RELEASE NOTES UPDATE Web page describes the problem:

   VISUAL BASIC 5.0 RUN-TIME DLL CARRIES READ ONLY ATTRIBUTE
   Under some conditions during Windows NT 4.0 Option Pack installation,
   the Microsoft Visual Basic development system 5.0 run-time
   dynamic-link library (DLL) (MSVBVM50.dll) is marked with the Read-only
   file attribute. This causes errors when running any setup program
   created by the Visual Basic Setup Wizard, or in some cases causes an
   error with Visual Basic-created components that are downloaded into
   a browser.
