I had twice in Vanilla > BF > Renpy > Mod and got the wardrobe fail.There is no correct or incorrect order. You just need to put the files in correct location as described here:

Moment I did Renpy then BF it got the Position Error that when line edited allowed launch, that however threw errors left right and centre in game.
There is obviously something wonky if you doBF then Renpy rather then Update > BF since it threw the exact same error both times from clean extract.
Anyhoo, time to unpack the "just needs mod" archive and slap in the stable-ish March 8.
