CAUSE

In this particular situation, this error message can occur if you have the wrong version of the MSVBVM60.dll file registered in your system (or are distributing the wrong version of MSVBVM60.dll with the Package and Deployment Wizard). The wrong version of MSVBVM60.dll may be installed if you installed Visual Basic 6.0 Service Pack 4 (SP4) or later and if your version of MSVBVM60.dll is earlier than the version that shipped with Visual Basic 6.0 SP4.

RESOLUTION

To resolve this problem, make sure that the version of MSVBVM60.dll is the same version that is distributed with Visual Basic 6.0 SP4 (which is 6.00.8877 for SP4 and 6.00.8964 for SP5). MSVBVM60.dll is located in the \WINNT\System32 or \Windows\System folder.

To make sure that the proper version of MSVBVM60.dll is being distributed, place a copy of this file in the \Microsoft Visual Studio\VB98\Wizards\PDWizard\Redist folder.
