THIS APPLIES TO ALL MOD MANAGERS - FOMM, NMM, MO, and etc
I am posting this just in case anyone runs into "A Problem Occurred During Install: The File Exists" and wants to save themselves from anger, frustration, grief, Nuking/Gecking (Uninstalling/Reinstalling) their game a few times, and the Dark Side. Of course, hopefully they search the forums before doing anything drastic.
The fix is to clear out this directory ...
c:\users\<your username>\AppData\Local\Temp
You probably can use Accessories > Systems Tools > Disk Cleanup. If you do it yourself, it is a hidden file and will need to unhide it. And if you know all of this, then this is for the ones that don't or not thinking it is the cause.
PROTIP: Instead of unhiding hidden files, you can open a file browser or explorer window and type %appdata% in the address bar. This will place you in AppData/Roaming. Then just move up a directory. The files inside AppData aren't hidden, just the directory itself. --TJ
