DllNotFoundException on 1 of 3 computers.

Unity Engine
1

A friend and I are working on a game and are using raknet.dll built from RakNet 4’s swig package to make RakNet code directly accessable from c# / unity.

I have tried on two computers a 32bit Windows 7 computer and a 64bit Windows 7 computer. He is also trying to build this on a Windows 7 32bit computer however whenever he tries to play the game from within Unity he receives this error:

DllNotFoundException: RakNet
RakNet.RakNetPINVOKE+SWIGExceptionHelper…cctor () (at Assets/RakNet/RakNetPINVOKE.cs:106)

When he tries to play an exe build I made the script which includes RakNet does not function at all for him so that portion of the game code is completely gone when playing.

I am sure we have identical project files, we have removed the project files completely on all three machines and downloaded them fresh and received same results all around. He even tried an uninstall and reinstall of Unity. We have been troubleshooting this for a week and have not made any progress.

Does someone have an idea as to why this might be occuring only on one computer?

Thanks so much, really need help.

This had to do with some corruption in his Microsoft Visual c++ redistributable. He was not able to install a new MSVC redist without getting errors. Still not sure what the problem was, but he formatted his computer and it took care of the error. Too bad we couldn’t find a better solution. Good luck to the next person with this problem, took us over a week to solve =(
