I'm a dinosaur...still working with XP and I'd like to get a mod organizer for Skyrim.

BOSS is no longer supported (can't get a masterlist.txt file), and LOOT requires Vista or higher.

I've no plans to upgrade my OS.

Anyone have any suggestions? (be nice).

I don't think there are any other options. You could sort them manually either by trial and error or by looking at them in xEdit and deciding which of conflicting records should prevail. That's a fair bit of work though.

BOSS is still being supported, the Skyrim master list is frozen but the program is very much supported. Only the Oblivion master list is maintained but the others are still online and BOSS should grab them as normal.

Are you getting an error message or anything? And can you provide more details? If there's a bug somewhere in the program, I'd like to be able to track it down and squash it before the final version of BOSS is released for XP.
