Scenario
After upgrading the PC used for the machine, nothing seems to work, and although the Techno CNC Interface opens, it does so with errors.
Problem
This is a software/driver issue. The drivers for the PCI controller card require 32-bit Windows® because they will not function in a 64-bit environment.
Solution
At this time, the only solution is to provide the router with a 32-bit Windows PC, either by switching PC's or re-formatting the current PC with 32-bit Windows. See Computer requirements for more info.
PC's with a 64-bit processor can run 32-bit Windows (this means that it's fine if the PC has 64-bit hardware, but you must install a 32-bit version of Windows on it).
