A failure occurred during initialization: the network path was not found. How do I reinstall Powershell or resolve the existing path? Kind regards, Anthony May 1, 2015 at 10:29 am #24895 Matt McNabbParticipant I'm thinking this could be a user profile issue. Try logging in to Windows with a different user or recreating your own profile. Maybe something was corrupted in the upgrade? Author Posts You must be logged in to reply to this topic.
