When launching ArmA 3 Tools, the publisher will not load, I get a Publisher.App.HandleUnhandledException - System.BadImageFormatException: Could not load file or assembly 'SteamLayerWrap.dll' or one of its dependencies. is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)
File name: 'SteamLayerWrap.dll' when I try to open the Addon builder I get a Unhandled Exception: System.BadImageFormatException: Could not load file or assembly 'SteamHelper.dll' or one of its dependencies. is not a valid Win32 application. (Exception from HRESULT: 0x800700C1) error. Some of the other tools will load, others won't. I have tried uninstalling/reinstalling, messed with the regedit, deleted the userconfig for the tools and deleted the SteamLayerWrap.dll, then verify files. Nothing seems to work. Please help.

Hello can you try the steps posted here:
https://community.bistudio.com/wiki/Arma_3:_Unusual_process_exit#0xC0000135_-_STATUS_DLL_NOT_FOUND
Verifying ArmA in Steam, reinstalling DirectX/Visual C++ and running the File Check Tool did nothing. However, I ran the 64 and 32 bit version of Microsoft Dependency Walker and got a ton of errors for several hundred DLLs for the ArmA EXEs. Same results for ArmA 3 Tools and the Publisher EXEs.
The solution is presented on the following StackOverflow question:
https://stackoverflow.com/questions/50970449/error-800700c1-in-instantiating-an-object-for-microsoft-office-interop-excel-a
Deleting the file "C:\Program" fixes the issue.
That's a similar issue for Excel. Not sure if it even applies to your case.
Also Microsoft's Dependency Walker exes are too old and they no longer work on Win 10 afaik.
Did all the steps from https://community.bistudio.com/wiki/Arma_3:_Unusual_process_exit#0xC0000135_-_STATUS_DLL_NOT_FOUND. I even tried going to back to a restore point on windows from 3 days ago. Nothing.
Found a solution: After digging online installing Microsoft Visual C++ 2008, 2015-2022 seemed to be the fix. I’m unsure which one was the actual fix but I installed them all.
