How to tell the engine version of a Windows standalone?

[Ben Rubinstein]

I've been trying to make a very minor mod (replacing a logo!) to an app I 
built some years ago; but the client has a problem with it that I can't reproduce.

The easiest thing would be if the problem was caused by a subtle difference in 
the version of LC used to compiled the standalone - I made a quess for which 
version that would have been, it doesn't seem to help.

Does anyone know of a good way to analyse a compiled Windows standalone to 
discover which version it relates to?  (It would be easier on Mac because we 
can open the package...).

TIA,

Ben
