Q: Assassins Creed 4 Black Flag: AC4BFSP.exe Entry Point Not Found This thread is locked from future replies

When I tried to launch AC4 for the first time in a few months I got this error:

AC4BFSP.exe - Entry Point Not Found

The procedure entry pint uplay_r1.UPLAY_ACH_EarnAchievement could not be located in the dynamic link library uplay_r1_loader.dll.

Is there a fix, if so what is it?



Hi Matt,

when I launched AC4 first time I also got similar error, but I have a solution for it .

Follow below steps

1) Download those configuration files for AC4  :- orbit_api & steam_api

2) also download these .dll files for AC4 :- steam_api.dll, uplay_r1.dll & uplay_r1_loader.dll

3) replace these all files in the AC4 game directory.

4) and cheers you are ready to play.

and if also game doesn't start follow below steps

1) Disable your Windows Defender real time virus protection just for little time

2) follow above three steps (i.e. downloading those files & replacing them in directory)

3) start the game

4) If game successfully starts enable your windows defender real time virus protection.

then also AC4 doesn't starts  then I'm unable to give you any solution.


Did this solve your problem?

Sorry this didn't help.
