not being able to load dll files in other computers

Hi every one

Im trying to NETLOAD a dll file in other peoples computer but it doesn't load.

I even clicked on the unblock checkbox in the dll properties on the destination computer but still no luck.

this is the result:

Cannot load assembly. Error details: System.IO.FileLoadException: Could not load file or assembly 'file:///C:\Users\Island\Downloads\Force Layer and color.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)
File name: 'file:///C:\Users\Island\Downloads\Force Layer and color.dll' ---> System.NotSupportedException: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information.

at Autodesk.AutoCAD.Runtime.ExtensionLoader.Load(String fileName)

I was searching the issue which I came up with this

is there anyway to make a dll trusted before sending it to some one?

I also saw Kean's website which pointed this issue:

but I can't access every ones acad.exe.config file on their computer.

I also noticed I cant edit that file in wordpad or notepad.

You have to unblock dll-files: https://winaero.com/how-to-unblock-files-downloaded-from-internet-in-windows-10/

Are you sure you unblock not only this dll-file but also all dependent dll-files?
