When I try to open my launcher it says that some files are missing. I tried to reinstall the program but that didn't work. So I factory reset my laptop. This fixed it for a day. But I can't factory reset every day to just play minecraft.

I was playing minecraft perfectly up until tuesday. The day before yesterday when I tried to open up the minecraft launcher, it showed me that some files were missing. So I tried deleting and reinstalling 4 times. Then I factory reset my computer after saving everything valuable to a pendrive. After the reset was complete, I installed minecraft and then opened it up. It still didn't work. Then afterwards I decided to ask my friend who has minecraft as well, what he might think the problem is. I opened it as to prove a point but it opened! The launcher worked perfectly. But Yesterday, when i opened the launcher, the glitch came back. I can't factory reset my computer every single day! What do I do?
