Hey,
I got to the very final stages of getting Morroblivon but everytime I opened Wrye Bash and tried to click on the Installers tab it would crash. I figured I would just uninstall it then install it again. When I went to install it again, itstead of going though all the specifics, it would just say 'Congratulations the installer the detects that you have a full install of all the prerequisites already!' So I click next and instead on having that Oblivion tick box, it just has one that says 'Install Wyre Bash to extra locations'. What do I do? Before you ask, I have Vista, I installed Oblivion into Program Files and I have disabled UAC.
Thanks.

When in doubt, uninstall
When in doubt, uninstall everything and start over, installing Oblivion to c:\games\oblivion\ or something outside of program files. Backup your save games folder (in 'My Documents'), then uninstall everything using the windows control panel (including python etc) and when that's done, manually delete all of the folders related to Oblivion, including the one in 'My Documents'.
Probably not what you wanted to hear, but sometimes that's what it takes...
