It's not that simple. 1998 is at most LabVIEW 5.0, and possibly LabVIEW 4.1 (5.0 was released in February 1998 and may have been used for this program, or it may not).

You may be able to get it to run on Windows XP as it is possibly a Windows 95 version but it could just as well be compiled for Windows 3.1 and that can not run on any NT kernel.

Yes those executables were in fact an LLB tacked onto an executable stub. But that LLB still had only the front panels that were ever shown, and no diagram at all for any of the VIs in it.

Yes, I remember in ancient times being able to rename a .EXE to .LLB then being able to look inside.  As I recall, it was possible to build  .EXE  with the block diagrams.  If that is the case here (unlikely), extraction of the source code would be easy.

With the old versions of LV all VI had to be in a LLB file to able to create an executable.

The executable were rather large because they also hold the run-time.

As far as I know it is not possible to retrieve the source from the executable.

The executables from Steve work fine in XP.

Thanks to KC for the help. Indeed, running them in a Windows XP VM works.
