I have acquired a very nice Roland CNC engraving / milling machine that is in mint condition and works without fault. It is maybe 15 years old. I have the CAD/CAM software and a 32 bit driver but am currently limited to using Windows XP only. The driver is Win XP / Vista / Windows 7 compatible and I have instructions from the reseller to install on a 64 bit operating system (the instructions, unfortunately, do not work at present). Elsewhere on the internet I have found instructions to perform a firmware update to a fully 64-bit system but the update appears to require Windows 7.
I am presently stuck using Windows XP (because I have a copy) and cannot progress to using Windows 10 (which I have running and licenced on more than one machine). Windows 7 is available to download from Microsoft with a suitable product / licence code which I do not have. There is no option to purchase a code from Microsoft.
Basically, I need to install Windows 7 (32 bit), perform the firmware update, and then remove Windows 7. I'd rather not purchase some fake codes from eBay. Any suggestions?
