Just to chip in that I am one of those that has 17.17.2314 working fine on XP SP3 Pro. I didn’t need to do anything special just normal update when this version was released.
The GUI is slow to fully load, as documented by others and is by design. I find it no different from running on Win10, except some peculiarities with SmartScan, but that is another story and subject of a separate thread.
