if its prepatching then why does it keep happening every time i close the game?
Did you allow the patch to finish? If not then it will continue to try and complete the patch each time you close.
If you did allow the patch to finish then it will check for the patch each time you close, but should stop and self close when it finds the complete patch.
Sometimes... The patching service hiccups and I've heard of a few pre-patchers on LoR and certain updates getting this continual cycle of patching.
Personally whenever I see that my launcher is pre-patching I hit the cancel button, right up until the release date patch as I don't see the point of pre-patching code that hasn't passed through Tribble without problems.
I'll probably take a couple of weeks off when DR hits Holodeck to let the dust settle, so the first patch I'll get for DR won't be until then. IIRC the pre-patching is separate from the regular maintenance patch so will not be installed by default.
I have the same issue as others describe here.
It tries to patch the game every time I close STO or start the launcher.
It never finished, only goes part way through hand then stop, which means it repeats the process every time.
