RESOLUTION

To resolve this issue, use the appropriate method:

Method 1

If you receive the error message when you try to run a Visual Basic 3.0 program in Windows, reinstall the Vbrun300.dll file. To do so, reinstall the Visual Basic 3.0 program that includes the Vbrun300.dll file on its Setup disks.

   • The Win95_04.cab cabinet file on disk 4 of the original Windows 95 non-DMF floppy disks.
