VB3 PRB: Making .EXE Error: Wrong Version of Runtime DLL

• Microsoft Visual Basic Standard and Professional Editions for Windows, version 3.0

SYMPTOMS

If a copy of an executable is running on your computer, and you try to create a new executable with the same name, you'll receive this error:

Wrong version of runtime DLL.

Unexpected error quitting.

CAUSE

This error is caused by the fact that Windows doesn't load a new copy of a module if it thinks the module is already in memory. Because one instance of your .EXE file is running already, attempting to run the re-compiled version really just increments the usage count of the .EXE that is already running.

The Visual Basic error occurs because VBRUN300.DLL tries to open the .EXE file and read resources out of it. But the .EXE file you're reading from is different from the .EXE file that is actually running (because you did a 'Make EXE' over the old one), so VBRUN300 has problems. It signals with the "Wrong version of run-time DLL" error. It reports this error because it is under the assumption that because it could not read the .EXE file, it doesn't have the correct version of VBRUN needed to execute that .EXE file.

RESOLUTION

To work around the problem, either rename the .EXE when you create a new executable, or exit from the executable that is currently running.
