Scenario
After upgrading the PC used for the machine, nothing seems to work, and although the Techno CNC Interface opens, it does so with multiple 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. (PC's with a 64-bit processor can run 32-bit Windows, though PC's with 32-bit processor cannot run 64-bit Windows. This means it is to your advantage to have 64-bit hardware since you can run either version of Windows, but you must install 32-bit Windows on it)
