I can't reinstall Firefox after uninstalling it. I did not delete my old Firefox data file and have another file on Program Files called Firefox (7).

I was experiencing problems with the internet whenever I used Firefox so I uninstalled Firefox maintenance, and then uninstalled Firefox using Advanced Uninstaller software. I then realized there was another file called Firefox (7) on Program Files which I have placed in the Recycle Bin. I still have my User data called "Old Firefox Data" on the Desktop. I have tried to reinstall Firefox but Firefox warns me I will have limited access and won't let me run it using my current user name and asks me to do "Administrator" which I don't use on my personal laptop.

Thanks for all the help!

The full setup for Windows is on http://www.mozilla.org/en-US/firefox/all/ (link below green button) as the green download button on mozilla.org serves the stub installer.
