Cannot launch game - PLEASE HELP

Recommended Posts

Please help -


I have played Squad for over a year now and had no problems at all until I recently updated to Windows 10 and did a fresh Install.


I now get an Error when launching the game, a message pops up "The application was unable to start correctly (0xc0000142). Click OK to close the application" Then


When you click OK a message from windows pops up


"PostScriptum.exe untrusted system file (C:\\Windows\System32zdwmapi.dll)" Anyone know how to fix this?


Fixes i've already tried that don't work:

-Uninstalling easy anti cheat

-Verifying steam cache

-Disabling Windows defender

-Disabling anti Virus

-Run as admin 

-Repair EAC


I also get the same message when trying to run the Post Scriptum BETA.


I love this game and i'm worried I won't be able to get this fixed i've looked at other peoples posts on here and nobody seems to have resolved this issue :(

Untrusted System File

Repair missing or corrupted system files.

Run the following command with Administrator rights to repair corrupted system files. sfc /scannow

Check the following ;

See if your Anti-Virus is interfering with Squad or EAC
Try to repair EAC 

and finally do the following 

1. Open Cmd.exe by admin

2. Type sfc /scannow and hit enter

3. Let the scan run itself.

4. If the result says "some of the files were corrupt and wasn't able to fix them"
    Read this : https://appuals.com/fix-corrupt-files-reported-sfc-using-sfcfix/

5. When the scan finishes w/o any problem,  Type shutdown /r /f /t 0 - It will automatically reboot your system.
