Then please use `Open Source' or `Free Software' so it is clear that
you don't mean zero-cost.

The tools are the StatConnector server .exe and .dll, and those are GPL.
On the other hand, Windows is not free, so I think you need to use a
different operating system.

There are no Open Source versions of Visual Basic, either.

Not true.  It uses msvcrt.dll, for example.  DLLs are DLLs, no
