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
7. Delete the DbgHelp.dll file.
8. Alternatively, you can Cut the file and safekeep it in another folder just in case. However, it’s likely you can recover it by Verifying Game Cache.
9. 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)

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

The fix, with screenshots

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

• Head over to your Steam Library

• Right-click Watch Dogs 2
• Click Properties

• Go to the Local Files tab

• Click Browse Local Files.

• Access the bin folder

• Delete the DbgHelp.dll file.

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.
