I tried searching this and other forums and can't seem to find usable info. I'm using Windows 7 and when I install Oblivion, I don't get any options for choosing the installation path, so I can only install it in the default x86 folder. I've tried looking for Oblivion in the registry and can't find it there, and when I called Bethesda (which was some old advice on a forum a year or two ago somewhere) to ask about how to change the installation path in the registry, they told me that Windows 7 doesn't support Oblivion so they can't help me. I've heard rumors about being able to do that, but so far have not found any concrete descriptions of a solution that works. Morrowind isn't a problem - during installation, I can choose the installation path.
Has anyone been able to deal with this?
Thanks,
Josh

Sins when do you need to
Sins when do you need to install a game to run it?
When a program is on the HD it should run.
I don’t even have Oblivion installed and it runs.
I am on Windows XP but that should not matter.Got multiple Oblivion folders on my HD and they all work.
