Searched everywhere, can't find a situation quite like mine. One day, the Creation Kit was working, the next day it wasn't. Splash screen comes up, the main window is visible, it gets to "initializing archive" for a few seconds, and then it just closes itself. No messages, just gone. (Up until here, the problem seems relatively common.) Tried some ini edits I found online... no change. Tried removing all mods... no change. Copied the entire Skyrim folder to my secondary drive in case I mess up on my next attempts. Tried to run creation kit from there and it worked. So at least I have a workaround. Move everything, make changes, move back. But I'd like to solve the problem. Probably something to do with being on the same drive as my OS. Maybe a Win10 update is causing it to be blocked? Any ideas? Thanks Update, before someone chimes in with the easy ones: -disabling firewall does not work -disabling anti-virus does not work -running as administrator does not work
