It is possible that other software on your computer is using files in the Firefox program folder.
Did you try to reboot the computer or delete the Firefox program folder (C:\Program Files\Mozilla Firefox\) manually via Windows Explorer?
You can also try to boot windows in Safe mode (F8 at boot screen) to see if that allows to install Firefox.
