“AC4BFSP. EXE failed to load correctly” is an error that occurs when you do not grant the necessary permissions to Assassin’s Creed IV Black Flag.

A lot of desperate players even thought about quitting the game just because of this error. I wanted to help them 🙂

Note: I have been told that this also fixes the following errors:

“ac4bfsp.exe entry point not found”

“the application was unable to start correctly”

“ac4bfsp.exe has stopped working”

Fix 1: Run AC4BFSP.EXE as an Administrator

• Close Steam client.
• Open Windows explorer.
• Go to the installation folder of Assassin’s Creed IV Black Flag (This is default location: “C:\Program Files (x86)\Steam\SteamApps\common\Assassin’s Creed IV Black Flag“).
• Look for “AC4BFSP.EXE” file.
• When you find, right-click on it and press “Run this file as an administrator“.
• Launch Assassin’s Creed IV Black Flag.

“AC4BFSP.EXE failed to load correctly” error and the other errors that I mentioned above should be gone now 🙂 Don’t forget to thank me guys 🙂
