Fix Watch_Dogs 2 not starting (Multiplayer enabled)

A guide to fixing Watch Dogs 2's launching problem

The fix that worked for me (Multiplayer works, too)

For this fix, we need to delete a file in the game repository.

1. Head over to your Steam Library

2. Right-click Watch_Dogs 2

3. Click Properties

4. Go to the Local Files tab

5. Click Browse Local Files..

6. Access the bin folder

7a. Delete the DbgHelp.dll file.

7b. Alternatively, you can Cut the file and safekeep it in another folder just in case. However, it's likely you can recover it by Verfying Game Cache.

7c. There might be a third method: Renaming the DbgHelp.dll file to something else so the game doesn't recognize it, and considers it deleted. Would appreciate if someone confirmed this (You will be credited)

7c. Thank you Lazahrus (76561198003339259)!
Renaming DbgHelp.dll works, with a minor remark: read below for more information.

Originally posted by Lazahrus:

Confirmed, it works renaming just the file. I would also like to add that I had to do it in the bin_plus folder, instead of the bin folder.

That's it! I really hope this fixed your game. I have been reading the the support page of Ubisoft and browsed pages of Steam Discussions until I found this fix.

That's it! I really hope this made you able to launch your game successfully and made it worth your money.

A fix that worked, but disables Multiplayer

For this fix, we need to add a launch paramater to the game. Keep in mind this fix disables multiplayer; since it disables the anti-cheat software EasyAntiCheat, which is required for online play.

1. Head over to your Steam Library

2. Right-click Watch_Dogs 2

3. Click Properties

4. Click Add Launch Paramaters..

5. Paste this in the field:

-eac_launcher

This fix is much simpler. However, remember this fix disables all online features.

Follow these steps as a last resort

For your convenience, this list is ranked from easiest to follow, least time-consuming (•) to more time consuming (•••)

You can try:

this did not work for me

[gamer14asd]

I tried everything in this guide, even the -eac_launcher fix and it doesn't work. It just quits after the splash screen.

[Der Jumper-Kai]

did not work for me.. but if i go to the game files and start the EAC.exe it launches a small loading window, but from there nothing happens...

[Stardog]

"-dx11" in launch parameters in Ubisoft Connect 100% worked.

I'm unable to find the bin_plus folder. Where would this be located?

[Monsieur Ethan]

not worked

[Kerolyte]

ikr? i'm glad it worked for you 🤍

[FatBrioche]

Deleting the dll file (I just moved it to the parent folder actually) worked. Never saw a fix as weird as this. Thanks!

[Baby BronZe]

[[MEAT]Sorrow]

I found a different fix. I downloaded Display Driver Uninstaller and uninstalled any intel drivers my PC may have had (I use NVIDIA) and now the game launches perfectly.
