FOMM crashing while installing TTW

[BelGarion]

Alright. So I am trying to reinstall TTW with FOMM (0.14.14) like I've done hundreds of times before and this time it crashed during install. I go into the Package Manager and choose the TTW Main Files package, click Activate and after a little while a pop up box appears with a series of questions. They are :

So... I am at a loss, what did I break? O.o

Didn't run as admin most likely, or the default ini is read only.
