i have a mod pack (http://www.technicpack.net/modpack/details/ather-mod-151.66372) and every time i try and install it it said "please select an install directory" so i made a folder in .technic and selected it but it said "Please select a directory outside of C:\Users\RT\AppData\Roaming\.technic" how do i get it in side the folder?
