When I open it even from the .exe with admin privileges it just boots the nGuard up, flashes a black screen, and then closes everything like it never even launched. I've tried everything afaik:

• Removing GameGuard folders
• Remove %appdata% folders (this includes user configs)
• Uninstall/Reinstall GGSetup
• Windows 8 compatability
• sfc /scannow
• Updated GFX drivers and chipsets
• Uninstalled/Reinstalled Helldivers 2
• Verified game files through steam
• Disabled Steam Input
• Disabled all overlays
• Disabled antivirus and added exceptions to firewall and antivirus/ransomware protections
• Repaired and installed "Visual C++ Redistributable for Visual Studio 2012 Update 4"
• Tried dx12 and dx11 launch commands in Steam

I'm at a loss for what to do, at this point I'm just going back to Warframe until something is fixed. I believe it's something to do with nGuard not booting correctly, like it's being blocked, but by what? I don't know.

Edit: Found on Arrowheads Zendesk under "Known Issues"

Game launch failing due to GameGuard errors

The Problem: When this problem arises, players can’t start the game at all.

 

Why It Happens: The anticheat software is catching false positives.

 

Frequency: About 1 in 150 players are reporting this issue. But when it does happen: it’s happening all of the time.

 

What We’ve Done / Are Doing: We’re working with the anticheat vendor to see what adaptations we can make. When we do have solutions, those will be rolled out automatically via the anticheat on game start.

 

What Players Can Do: We’ve learned that one workaround is to close other running software. We’ve found that the game has a particular challenge running alongside antivirus, fan cooling, or streaming video overlay programs. We would love to have some community support here. If you identify programs that the anticheat software can’t get past, can you let us know? We can work on getting those legitimate programs whitelisted so you can keep them on and still run the game.

So I guess that's that, some of us are just shit out of luck until they find out what programs are triggering false positives for their anticheat.

Update: Fixed the crashing and reporting to Arrowhead

So I finnally figured out that Steelseries Sonar was causing the nProfect to false positive aqnd crash me on startup. All I did was go to Device Manager in Windows, find the drop down for Sounds, and uninstalled Steelseries Sonar.
