Solution 1 – Check your antivirus
Antivirus tools are a necessity, but if you can’t run Assassin’s Creed 4 Black Flag on your PC, the problem might be your antivirus. Sometimes a third-party antivirus tool can interfere with your game and cause this problem to appear. However, you can easily fix that simply by disabling certain antivirus features.
If that doesn’t help, you might have to temporarily disable your antivirus as a workaround. In last case scenario, you might even have to remove your antivirus and check if that solves the issue. Even after you remove your antivirus, you’ll remain protected with Windows Defender, so there’s no need to worry about your safety.
If the issue still persists, you might want to disable Windows Defender temporarily and check if that solves the issue. Another way to fix this problem is to switch to a different antivirus solution. There are many great antivirus tools on the market, but currently, the best are Bitdefender, Panda Antivirus, and BullGuard. These are all great tools, so feel free to try any of them.

Solution 5 – Reinstall the game to the C drive
According to users, they managed to fix problems with Assassin’s Creed 4 Black Flag simply by reinstalling the game to their C drive. Many users tend to install games on a different drive in order to save space, but it seems that Assassin’s Creed 4 won’t work unless you install it on the C drive.
This is a bit tedious solution since you have to install the game again, but once you install it, the problem should be completely resolved.
Solution 6 – Replace the DLL files
Assassin’s Creed 4 Black Flag requires certain DLL files from Windows in order to run properly, and if these files are missing or not suitable, you might encounter certain issues with the game. Many users reported that the game won’t work due to XAudio2_7.dll file. To fix the problem, go to C:\Windows\system32 and create a copy of XAudio2_7.dll. Save the copy to your Desktop.
Now go to the game’s installation directory and locate the Launcher folder. In there, you should find XAudio2_7.dll file. Copy that file to the C:\Windows\system32 and replace the old file. After doing that, the problem should be resolved and the game will start working again.
Several users reported that other files can create this problem as well. To fix the problem, first you need to navigate to C:\Windows\system32 and C:\Windows\syswow64 directories. Locate the following files, and copy them to your Desktop as a backup:
Now go to Assassin’s Creed 4 Black Flag installation directory and find the x86 version of the aforementioned files. Copy those files to C:\Windows\system32. Now locate the x64 version of the files and copy them to C:\Windows\syswow64 directory.

Solution 8 – Remove your save game files

Simply go to the game’s installation directory, by default it should be C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\savegames\<User ID>\<Number> and locate your save game files. Now move them to your Desktop and try to start the game again.
