Cannot Install Patch 1.4b

[Intrepid]

Hi everyone. After a long hiatus from playing this game, I got a newer system and want to install the GWX pack. As per their instructions, I tried patching the game from the Ubi site. When I tried to run the patch, I saw this:



I installed a clean version of the DVD which came as a 2-in-1 with SH2. I opted not to install Game Shadow, as I can conduct my own updates. I downloaded the patch for the retail DVD from Ubi too. I know the window states I am installing v1.3, but as indicated in another post, that is only a typo from the devs. I can't figure out what the problem is.

One thing I suspect is that it is already the correct version. The game I bought shows v1.4 . Is this actually 1.4b? I only bought it last year.

I am running Windows 7. My computer is more than capable of running the game.

Was I supposed to download all the previous patches individually or something?

Please advise, and thanks in advance.
