Thanks Olly. The card that comes with it states 4.0 for the .Net version but we are going to try this. The only issue we have with that is most of our machines in the company are running Windows XP. .Net 4.5 requires Vista or better. Oh well, time to upgrade.
I'll let you know how we make out. I've read elsewhere that a DLL needs to be registered as a 32 bit application however the windows error messages give you zero information as to what.
