When Glasswire 1.0.35b was released, I reported the following:
“Installing this update cleared my C:\ProgramData\GlassWire\service\glasswire.conf, which was being used to specify a custom database location. Updates should definitely preserve user settings, not simply discard them…”
(See: GlassWire 1.0.35b now available with translations)
Installing 1.0.38 just did the exact same thing.
