PC TERRARIA WON'T START

[tigermasterx]

I click on play but nothing happens.
I use windows 10 and when I open terraria server gives me this error:
Unhandled exception: System.BadImageFormatException: The file or assembly could not be loaded 'Microsoft.Xna.Framework.dll' or one of its dependencies. it is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)
in Terraria.Program.LaunchGame(String[] args, Boolean monoArgs)
in Terraria.WindowsLaunch.Main(String[] args).

Did you try to re-install the game?

It likely has to do something with this 'Microsoft.Xna.Framework.dll' thingy. Check if you might have changed something with it.

You have the same problem as me.

I have tried reinstalling Terraria completely, XNA, Dot Net, etc and nothing will fix it. And it's not exclusive to Terraria, this is all XNA games like Stardew Valley too.
The only workaround I found, which I have not done yet, is to downgrade to Windows 10 build 1703 and not allow Windows Update to update your build.

I believe it's related to updates KB4054022 or KB4057247 on build 1709 which cannot be uninstalled.
