System.IO.FileNotFoundException: Could not load file or assembly 'X' or one of its dependencies when deploying the application
I'm having a strange problem with deploying an application, which references an assembly, written in managed c++.
I've created an assembly X, compiled it and referenced it in an exe file, called Starter.
Starter.exe starts normally on local mashine. However, when I copy ALL contents of the starter debug folder to a virtual mashine, and try to start it there, it crashes with following exception:
Unhandled Exception: System.IO.FileNotFoundException: Could not load file or
assembly 'X' or one of its dependencies. The specified module could not be found.
This does not make any sense to me, because X is right in the same folder as Starter.exe.
What could be causing this problem?
UPDATE
I've examined the dependencies in Reflector on the target machine, and it was able to find files for all of those.
I've also changed the configurations to x86/win32 for all projects.
UPDATE
Here are the logs from Fusion Log (location: C:\FusionLog\Default\Starter.exe\X, Version=1.0.4538.22813, Culture=neutral, PublicKeyToken=null.HTM):

I cannot sign the assembly, as it references several other assemblies, which are not signed

... Could not load file or assembly 'X' or one of its dependencies ...
Most likely it fails to load another dependency.
you could try to check the dependencies with a dependency walker.
I.e: https://www.dependencywalker.com/
Also check your build configuration (x86 / 64)
Edit: I also had this problem once when I was copying dlls in zip from a "untrusted" network share. The file was locked by Windows and the FileNotFoundException was raised.
