So we've been hanging on to NXT for ages as the maintenance personnel have refused to look at ProWorx 32 since the "buggy" days. We have lots of momentums kicking around that don't really need to have their hardware updated just yet. We're really running into a wall though with Windows 7 64 bit OS since NXT really doesn't work on it anymore (as opposed to how it has not been officially supported but still works on a 32 bit OS). With Windows 7 already nearing the end of its life cycle, our IT guys are insisting from a security point of view that we have to move to 64 bit OS. So realistically, what is our best option? It seems like updating to Proworx32 is the easiest option, but is it really still buggy and as awful as it was to start with? What about Concept? Does it support 984LL or would we have to reprogram everything? We use Unity for all our new quantums, and I was looking at the 984LL add-in to Unity, but I think for that to work we would need to update all the momentums to Unity capable processor adaptors correct? We are looking at another 10 years before we are totally done with the momentums through our evergreening program.
