BadImageFormatException

So I've googled this, followed all these guides on how to fix the issue, and nothing has seemed to work. I know it was posted here before but the topic ended abruptly and there didn't seem to be any resolution. Whenever I try to run Stardew Valley on steam it says "Running" for a few seconds before going back to normal.

Going into my event viewer shows:

Error 1:
Application: Stardew Valley.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.BadImageFormatException at StardewValley.Program.Main(System.String[])

So far the solutions that I've found and done are:
- Uninstall & Reinstall
- Run as administrator
- Run in compatibility mode
- switching the spots of the DAUDIO1_7.DLL files for the 64-bit windows
- reinstalling the XNA files
- the .NET says I can't install it because the most up to date version is added.

I can run more taxing games, so I know its not my pc not able to handle such a game, anyone have this issue that fixed it in a way different than all those?


EDIT: downloaded Terarria to check something and it has the exact same issue.

 

Hi @iSanyu. Can you install SMAPI, try it again, then post your SMAPI log when it crashes?

 

Unfortunately theres no error log folder in my stardew valley appdata folder. When I start it it creates the cmd window, then posts:

Unhandled Exception: System.BadImageFormatException: Could not load file or assembly 'Microsoft.Xna.Framework.dll' or one of its dependencies. is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)

at StardewModdingAPI.Program.Main(String[] args) in C:\source\_Stardew\SMAPI\src\SMAPI\Program.cs:line 97

And then it crashes.

 

@iSanyu Try this:

1. Uninstall XNA Framework.
2. Run C:\Program Files (x86)\Steam\steamapps\common\Stardew Valley\_CommonRedist\XNA\4.0\xnafx40_redist.msi to install the specific version the game uses.
3. Restart your computer.
4. Try to launch the game.

Does the problem still happen then?

 

Yes, I uninstalled it and tried to reinstall but I needed to have visual studio 2010 so I downloaded that as well, reinstalled XNA, same issue.

 

You ran that specific installer, you didn't download XNA Framework yourself?

 

I've done both actually, the first time I ran that specific installer, when that didn't work I uninstalled it and re-installed it using the microsoft website.

 

@iSanyu Which version of Windows do you have?

 

Windows 10, 64 bit.

 

@iSanyu Can you try running the .NET Framework Repair Tool, restart your computer, and then try the game again?

 

I had the same Issue as iSanyu and tried every fix I found
(I was trying to run the game on a Windows 10 64 bits)

so I found a post about this same issue: [link]
And the same person having this issue posted a solution that worked for him:

I tried this and it worked for me too! The game is opening now

But be careful to not mess up the Windows sysWow64 and system32 folders and do this procedure at your own risk!

 

I have the same problem too! i did everything reinstall everything(except for the stardew valley since i can't update it to v1.3 i lost my steam authneticator) im using the Smapi 2.5 its wsa working before but after months of not playing and i tried to play the the game yesterday i have this error there;s no error logs on the appdata or i reinstall the XNA switch the daudio

 

Wait mine is actually STARDEW VALLEY not XNA! so how do i fix it?

 

@juljimmy1 That usually happens due to...

• a virus on your computer changing Stardew Valley.exe;
  
• or using some pirated versions of the game which change Stardew Valley.exe for some reason.

If a virus scan doesn't find anything and you're not using a pirated version, you can ask for help in #support on the Stardew Valley Discord.

 

Thanks got it Fixed i scan my pc there's a virus called Ground exe now i can play it! thanks for the reply ^^
it renames the program to gStardewvalley.exe maybe that's why i cant play some of my games like League and PUBG.

 

Hey I am getting a similar issue please help

This also seems to happen with most other mods
