I only use TSRE for a few things because there has been no good instruction manual or document for it. I have all the
tips & tricks as well as the daily comments from ElvasTower but there are too many quirks for me (I'm almost 82) to
learn anew. I do have one route that has a fatal error in RE or MSTS, but not TSRE or ORTS and so I will likely try to
do part of it with TSRE but track & roads are already done, so the really quirky things will not get involved, like
turning off or on the automatic saves to the databases etc.
As for XP, I have one machine that still has XP on it.
