According to w3counter.com/globalstats.php for September, Windows XP is still used by 46% of the world's PCs.
I am still uncertain whether your reply covers the question: Is PDF24 Editor 2.8.6 compatible with Windows XP?
I run XP SP3.
When I got to the "Hardware Installation" screen, I was not installing hardware, so I went ahead with "Continue Anyway".
What are the implications please? Will this damage my system?
