In 3.6.1, the manual, section 3.1.3, has this to say:

"Your administrator will need to activate the “Enable Win32 long paths” group policy, or set the registry value HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem@LongPathsEnabled to 1."

Separating a value name from the key path with an @-sign, which is what the above is doing, is something I have never before seen anywhere. I suggest changing it by either:

- replacing the instructions for the manual change with a link to <https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx#maxpath> or a more suitable reference (I could not find a KB article when I looked)

- rewording it as, e.g.,

  ... in the registry key HKEY_...FileSystem, set the REG_DWORD value LongPathsEnabled to 1

  The value type could be left out; the value is predefined on all platforms where it will be effective.
