    Assassin's Creed iv Black flag not launching

    I bought AC IV today, downloaded it and it didn't launch. Then i reinstalled it and it didn't work. I've tried running it in adminstration- and Compatabilitymode. I am on windows 10. Please help me!

    I was having the same problem a few weeks ago! I uninstalled Logitech G-Hub and Logitech Gaming Software, and this seemed to fix the launch issue for me.

    Something we would also advise, to rule out any third party programs conflicting with the game is starting with a Clean Boot. This will disable any background programs, and can be done through the steps here

    Please also make sure that you have downloaded the latest drivers and system updates for your Computer.

    Thanks for getting back to us.

    What are your system specifications?

    Please try launching the game from a different User profile on your computer, which can check if there's any issues on the rights/registry side. You can do this through the steps in the guide here.
