The support to deploy on a remote machine is broke the
default behaviour on the Windows OS, so now it always
needs to set the $PATH manually before using the scripts.
Also, the new functionality didn't work on the remote
Windows machine because the scripts change the $PATH on
the local system only.
This commit adds some more checks and fixes the local
$PATH setup. It didn't check remote system requirements
so deploy on a remote machine still have some problems.
Added several messages in the scripts.
Also this commit contain increased timeouts to fix
failures during network interfaces add/change operations
on some Windows systems.
