Cannot load assembly (hr = 0x80131018)
===

I have a user with issues loading a .Net assembly into AutoCAD. I get the following error:

Cannot load assembly. Error details: System.BadImageFormatException: Could not load file or assembly (hr = 0x80131018)

They are using an anit virus package called Endpoint Security and when this is turned off, the load works.

I am not a .Net expert and was hoping there might be a friendlier solution than me suggesting the user put their anti virus package in the trash!? But I've no idea where to start, any help would be greatly received.

Thanks
