Hello!
How did you transfer the project? Did you copy the entire project folder, or did you clone it using git or some other scc software?
It looks from the error that the client dll did not survive the transfer, so one thing you can do is check that all the EyeX framework scripts and plugin dlls are still present under Assets/*.
You could also try reimporting the EyeX Unity package on the other computers, since that might also fix the problem if the problems are a result of a bad copy 🙂
Cheers,
