What I was probably actually hitting was exe caching issues where the
binary was updated on a SMB shared drive and I tried to run it with
the GUI exe still open, so Windows blends the two pages together and
causes all sorts of random corruption. I didn't know about that at the time.
Now, just call tryFixLogStateLocation unconditionally. The func itself will
bail out early on non-applicable OSes. (And rearrange it to return even a bit
earlier.)
