This specific guide is for if you receive the following error as shown below.  

Overlay Hook Failure
Curse was unable to start the in-game overlay for your game.  It has been disabled to prevent future game crashes.

Security Software

The most common cause is usually an antivirus program that’s stopping Curse from injecting into the game.

If you are running a security program such as, but not limited to:

  • Avast!
  • Avira
  • McAfee
  • ESET
  • AVG
  • Kaspersky
  • Norton
  • Bitdefender
  • Microsoft Security Essentials

Try temporarily disabling your security program and running Curse again to see if there is any change.

Other Overlay Programs

Another possible cause is another overlay program interfering with our hooking process.

If you are running another Overlay Program such as, but not limited to:

  • Raptr
  • Plays.tv
  • Overwulf
  • OBS
  • Discord (with overlay enabled)

Try exiting them completely (or disabling the overlay) and running Curse again to see if there is any change.

Out Dated Graphic Card Drivers 

Another possible cause is that your graphics card drivers are very out of date, but in that case you should also get the error related to having an old graphics card driver.
