Possibel black screen fix...
I had the problem all day with none of those being apart of the solution. Unplugging did nothing for me. The problem was just solved for me when I ran CCleaner on my registry and fixed all the issues there. There were only a few as I just reinstalled windows 7 pro x64 yesterday. Then I ran a chkdsk /f :c in a command prompt with elevated permission... ie as administrator and restarted my computer. The computer did a check disk on the C drive and once it was finished and I ran the game, it ran like a champ. It's crap programing through and through. But unplugging stuff only is an issue for some. A lot of others out there are good to go with doing what I did.
SOLVED!!! No more Black Screen/Non-Launch on Far Cry 4
This is more of a workaround than a solution... but nevertheless, I got the game to finally work after spending my entire evening troubleshooting a game I pre-purchased for $60 and which I believe should be ready to play on day one!
Here's what the issue turned out to be for me....
- I unplugged my Saitek Eclipse Gaming Keyboard (model # KU-0418) and launched Far Cry 4. Low and behold... it launched for the first time!
- I setup my game options, then quit the game (this step is optional).
- To confirm my theory, I re-plugged the same Saitek Eclipse Gaming Keyboard into USB and tried to launch the game. Same black screen.
- The final confirmation came when I dusted off a regular Logitech keyboard I had and plugged it in and the game launched without issues.
Seems like the game isn't reading certain USB peripherals correctly. I'd say the keyboard is a pretty big deal. However, if you really want to play the game and have another keyboard or can play with a controller - this workaround method might work for you. Definitely give it a try. I'm about to go update my support case I filed with Ubisoft Support tonight. Kinda sad that I have to figure this issue out on my own... Get with the program , UbiSoft!
