--- Comment #6 from Nicholas O'Connor nrfoconnor+wine@gmail.com --- Sorry for the delay, I haven't had time to build Wine again until now.
Built a completely vanilla wine 1.7.29 with the following configure command:
% ~/winesrc/configure --prefix=/opt/wine
Then ran the Oblivion Launcher with this command:
% WINEPREFIX="/home/nick/.wine-vanilla" /opt/wine/bin/wine ./OblivionLauncher.exe
The Oblivion Launcher behaved perfectly. Once I manually updated the registry so the launcher knew where it lived, I was able to change my graphics settings, load and unload mods, and even launch Oblivion itself. The overrides list in winecfg for this prefix is completely empty. It seems this bug has been resolved.
