How to install monitor drivers manually?

I'm running Windows 7 64bits, and I need to install Dell 2407wfp drivers. The only issue is, the drivers from the website does not execute right after I download them, like they are supposed to.

If I try to manually install them (update driver in the control panel) I get a message saying that I already have the best drivers, and the the installation ends there.

Any ideas what could I do?, I get a couple of files an a .inf files I think it's used for this purpose. But no idea how to force Windows to accept them.
