Excel 365 32 bit version error

[Rich Russell]

I receive the following error message when the my addin is attached 

Initialization [Error] External library could not be registered - Path: packed:XLSYS_MAIN : BadImageFormatException - Could not load file or assembly 'XLSys_Main, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. This assembly was compiled for a different processor.

Hi Rich,

 

You should be sure to compile your main add-in assembly for “Any CPU”.

You might have some other settings in your project.

Hi 

Where I'm working we're doing the O365 migration and for my ExcelDNA as used the 64bit version.

Thanks

Your Excel-DNA can run on 64-bit office (the build normally outputs two version, for 32-bit and 64-bit automatically).

But your main add-in assembly should still be built as a pure managed assembly (targeting ‘Any CPU’).

It was built for 'any cpu'. The 64 bit version works but the 32 bit version generates the error.  I am confident the 32 bit version was loaded on a 32 bit unit.  Any ideas?
