VC++ code - Using a C# dll which refers another VC++ dll

Question

In my project we are working on different platforms java, C#.net, VC++ . My problem is related to calling C# code from VC++ code.

I have written "plugin.dll(VC++)" to communicate between device and UI. They provided "device.dll(C#)"[Third Party] with device

Below are the steps I did to make it working, please tell me where m wrong :

1)I have created one "wrapper.dll(C#)" which refers "device.dll".

2)To access "wrapper.dll" methods from plugin.dll I have registered it as "COM.wrapper.tlb" and imported in plugin.dll(VC++)
Followed below link, it was really useful :

3)Copied plugin.dll(VC++) in folder with .jar executable.

Everything is working fine on my system.Problem started when I gave this package(.jar + plugin.dll) to testing team.
It is not working on any other machine

Beyond your "plugin.dll", you have to deploy the "dll provided by device team" on the production server, too (and do not forget to register it there).
