I'm not entirely sure, but from what I can see from that screenshot and error message, it seems like you might be trying to install the 2.1=>2.15 patch. If it is your first time installing FH2, you need the FH2 2.15 Full Install, not the incremental patch.
On
this page, try downloading one of the "Full Download" files. If you used the torrent, download the first one on that page. The password for the .rar you get from the torrent is >>important-=-read-=-the-ReAdMe<< You shouldn't need a password if you download it directly from one of the other links.
Hope you get it up and running soon. I'm sure you'll have lots of fun with us on the battlefield.
