Hm. The most likely problem is that TES 111 won't be released for at least a few more centuries. Using software from the future tends to add a lot of incompatibilities.
Now, if you're trying to get TES III (3
) running, then you can do a few things.
First, don't install to Program Files in 7. There's a stickied thread for Vista/7 explaining those issues. Also, you should have patch 1.6.1820, and should probably go get the expansions if you don't have them. They fix a lot of issues and allow you to use mods that will fix more (the patch project may require BM, the code patch certainly does).
