The solution that worked for me was to edit the registry key to enable long path behaviour, setting the value to 1. This is a new opt-in feature for Windows 10
HKLM\SYSTEM\CurrentControlSet\Control\FileSystem LongPathsEnabled (Type: REG_DWORD)
I got this solution from a named section of the article that @james-hill posted.
