I un-installed Farcry 4 as I wanted to move it to a larger HD in my PC.
When I tried to install the game it stated that Farcry 4 was already installed. This was despite deleting all folders and editing the registry for this game.
I did manage to get the game via uplay and a 30GB+ download which I wasn't too happy about !
The game now takes much longer to load via the shortcut on my desktop ,stating that it is installing DirectX which I know is already installed.
How do I do a clean install with my DVD's?
Try uninstalling your Uplay client before installing the game from disc. Keep in mind that the Uplay client that is included with the DVD is likely out of date, and you'll want to uninstall that client once installation is complete and re-download it from uplay.com.
It's still more downloading, but the Uplay client is significantly smaller than the game.
Uplay will update the dvd Version every time
the Version that shipped on DVD was version 1.2.0
the current version is 1.10.0 .. rather then install all the patches incrementally it will download the full updated version of the game
several of the Far Cry 4 patches were QUITE LARGE and over a gig in size
