I had the same problem and I couldn’t sort it out. Miicraft staff couldn’t help me at that time either. I don’t know whether they found a solution yet.
The first thing I did was installing both Windows 8 and Windows XP in the same PC using multi boot, but that was a pain in the neck. So I ended up setting up an old system with old spare parts I had around and a $30 screen I bought at Cash Converter. Miicraft software doesn’t need much to run, so almost any cheap obsolete PC will be fine to bind it to the printer and make it work.
Sorry that I couldn’t help much
