It tell me that the specified path cannot be found. Any idea what is the reason of this error ?

Thank you for your help.

Answer 1

I resolved this issue by downloading the latest version of the binaries (v1.1.0-alpha ->v1.0.6).

Answer 2

In my case directories had too long path names. Shorting them solved the problem.
