Mod installation problem

I'm having problems installing the mod FFH II.
I dowloaded it from gameflood, but for some reason, it dowloaded a single item, that my computer does not recognize the format of. I admit, I have no experience using mods, this is the first one i've tried. I would really appreciate some help.

PS: I have BtS up to the latest patch (3.13) if its of any importance

And thanks in advance for any help offered.

It should be .exe file

Control Panel > Folder Options > View > uncheck 'Hide extensions for known file types'

It did nothing, GVBN, but thanks anyway. My computer shows it as a completely unkown file anyway. I would apreciate more help though. Please!

Again, thanks in advance.
