I am using a VB5.0/MSSQLServer6.5 based applicaton. SOmetimes (not always) when we navigate from one data entry screen to other screen, it show message 'This Program has performed Illegal operation and will be shut down'. On pressing the detail button the description is 'App xxx caused an invalid pagefault in Module MSVBVM50.dll at 0137:0f0513fd.'

I am not able to trace the reason. Interesting point to note is that , when application is run through VB5.0 there is no problem and when the exe file is run the problem occurs.

In need urgent help.

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