I hope this doesn't come as a surprise to many of you. For several (good) reasons, any further QLC+ will stop working on Windows XP. Support in the forums will stop at the end of 2020. I think it is time to move on from old hardware and software. I am also struggling to keep building QLC+ on a XP compatible framework, so there is a strong technical reason to this. Windows 7,instead, should be supported for some more time as Windows 10 is around since "only" 5 years now.
