WOW! I remember that from the early 90's.. Great game, I think it was one of the first to use MMX technology. which is now outdated. More than likely, its a 16 bit or 32 bit game, also, I don't know when the III came out but I know the earlier versions were optimized for pentium processors, probaby a P-200.  Modern processors would most likely run the game way too fast if it would run it at all.  There are some 'stifling programs' and converters out there but you stand a chance of bringing in a virus as in those days there were cracks and slowdown software that were purposely injected with a virus.

 EDIT:  Ignore the above, I just researched Siberia 3, It's not even out yet.

"Syberia III is an upcoming computer adventure game conceived by Benoît Sokal and due for release in 2014 or 2015."

I will leave my initial reply just for info purpose.
