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.
