Good Spot Moray didn't take much notice of the PC and assumed was same PC just fixed. It does look quite new so your probably correct could be 64bit.

Martin if this is the case then you'll need 32bit windows or another PC.

However I must agree with Lee that the Control box is Box of rubbish and with some dodgy wiring and practises. Ie: wiring 2 drives to one Motor output.
It may pay you to upgrade with better Controller that is Ethernet based and done correctly. This will allow to be run on 64bit PC and be much more stable.
