Hello guys, I'm new to parallels. I will start by saying the installation to Windows 10 was flawless and I'm really happy. However, my problems began when I tried installing Windows XP and the fact that no key in this world appears to work. I tried my own key from an HP desktop minitower that is deceased. When that didn't work of course I sorted to trying other options, tried another key from a neighbor laptop, tried hundreds of keys from the web, tried installing other versions of Windows XP, even tried the Spanish version thinking "if all else fails hey, I can always speak Spanish"! Nope, not happening. I have to sort to the obvious, something isn't working at all. Can someone shed some light? I was tempted to call Microsoft to ask them if they could sell me a key! What else to do, this isn't working! I appreciate it, thanks. Running latest parallels with Mojave on Mac mini 3Ghz.
