I have recently purchased a used AXYZ machine that the computer needed to be replaced I've replaced the computer the Windows 7 32bit (which I understand is what was used when the machine was originally manufactured) I installed the tool path software. When I start the software, an error comes up saying that it can't find the CNC. I've worked on a CNC machine before but simply doing the cuts never in the background, so this is unfamiliar ground to me. What am I missing, I’m hoping it's something simple

Thanks
