Running into some of the same problems from earlier in the thread, but I never saw someone come back saying a fix worked for them. So: ERROR(5): The directory name is invalid when running FNIS through MO. I'm on Vista, Skyrim is installed in Program Files (x86) (no other choice unfortunately), but UAC is off. MO is run as an administrator anyway. Antivirus is disabled (temporarily). The binary location is correct and the "start in" field is blank. This is the error: This is what makes it into my Overwrite folder before the error: And I've attached my log. I did have an accident where the XP32 Skeletons MO mod folder got renamed after installation, but I think I have it back to what it was. And I'm certain it's back where it was in the left pane, and LOOT doesn't move it in the right. Still, it's the only thing I can think of. Although, I was having some trouble with MO's virtual drive when configuring Merge Plugins Standalone for the first time. I was physically staring at the correct flag files in Skyrim\Data\Scripts\Source, but Merge Plugins (started through MO) couldn't see them. But, I know so little about this stuff it's probably nothing. Thanks for any help. FNIS Log.txt
