Then install this:

https://7d2dlauncher.blob.core.windows.net/installer/7D2DModLauncher.exe


Then



    Remove 7D2D from your system completely & manually delete any remaining files in the 7D2D folder that are left after uninstalling.
    Re-DL 7D2D on Steam.

    After it's finished downloading, right click and go to Properties -> Betas -> Choose 16.2. Wait for the game to downgrade back to 16.2.

    Now open 7D2D launcher and expand the "True Survival" on the top left. Highlight True Survival 16.2 and UN-Check "Use EAC" then click Play.
