Plugin Not Running On Some Computers

[structure1EKNKU]

Hi.

I have a plugin written in C# which is given to the end-users as a ZIP with *.dll, *.addin, and some config files depending on the plugin itself. On some computers (about 5% of the users with no clear difference between other users, I mean: they use the same versions of Revits as the others, the same versions of Windows, etc.) there is a problem while launching Revit after copying the plugin files to the proper directory (I am not citing word by word because it's originally in Polish):

The Revit program is unable to run the external application.

System.IO.FileLoadException

Either the file or one of its dependencies may not be loaded. Exception: HRESULT: 0x80131515

I cannot reproduce this error on my machine and I have no idea how to handle it. Please help!

HI @structure1EKNKU 

     This is load exception error, you need to unblock the dll once you extracted .Zip file. Kindly refer the below link to unblock the files.
