Using tolower and WeInstall I can install the fix, ub and tweak mods but not widescreen. As it's GOG it's a patched full install with correct torment.ini. I can get widescreen PT working on Win7 and with wine on Ubuntu 12.04 but I no longer use Win7 and it's really slow with wine on Ub, especially as I intend on modding BG later. Firstly, I know what the AR0100.wed error is for, its a location error.
