Answer 1

I'd suggest adding the directory path to PATH env variable in runtime, using the following code:

var dllDirectory = @"C:/some/path";
Environment.SetEnvironmentVariable("PATH", Environment.GetEnvironmentVariable("PATH") + ";" + dllDirectory);

That way, the change is only affecting the running process and is discarded when it exits.

Take a look at the documentation for LoadFrom and you'll find that it says: If a native image exists for assemblyFile, it is not used. The assembly cannot be loaded as domain neutral.

I believe you're going to need to add the DLL directory to the EXE's path.
