Making an executable file with the .vb extension?

[Eduardo-]

Thank you for testing. Maybe Visual basic is not installed on this machine? That could be relevant to how and why it works.

I have the VB6 IDE installed but not the .NET one.

I would attach the eVB Project files here to inspect, but the forum doesn't allow me to upload the .ebp or .ebf files (invalid).
Github eVB project files here: https://github.com/WindowStations/eVB

None of the three extensions have a program assigned to open.
