This is a clean install so I don't have any mods yet. 1st time running with it, just noticed that the actual FO4 and FO4 launcher executables don't work either from MO. They start up normally outside of it though.
For some reason, F4SE won't run from MO's drop down menu. The black cmd box appears for a split second, but then nothing happens. It works fine if I use the executable in the main game directory, but not from MO. Any suggestions?
