Oblivion Error Code -5001

[FuturePerfect]

I have been bored lately and so decided to get back into Oblivion. When I went to install it I foud I couldn't, instead i get the start up with the play option. I clicked on play i got an error message:

The Oblivion Launcher could not find the Oblivion game executable. Please reinstall Oblivion.

I then clicked on uninstall so I could reinstall Oblivion. Here is the error messages I next got:

I tried those things, I do have a folder in My Documents named "Important" containing 3 document files for the purchase of 3 offical mods and the 3 official mod's setup files, I think my purchase has expired now so I don't want to delete them.

Please help me

You are talking to your self in multiple threads. Lets stick with one. It looks like your last uninstall went bad or something. I would suggest a Registry cleaner to clean out your stuff and see if that clears things out and then try to reinstall.
