Unable to Install IPv6 Tunnel By Netsh Commands in Windows 10.0.10240

Hi all, I'm copying my own post (nearly) verbatim to Hurricane Electric's forum.

Running Windows 10 Pro 64-bit.

Given the suggestions of using these netsh commands to install an IPv6 tunnel:

netsh interface teredo set state disabled
netsh interface ipv6 add v6v4tunnel interface=IP6Tunnel 207.181.***.*** 184.105.253.14
netsh interface ipv6 add address IP6Tunnel 2001:470:1f10:111f::2
netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:1f10:111f::1

I get this result:

C:\>netsh interface teredo set state disabled
Ok.

C:\>netsh interface ipv6 add v6v4tunnel interface=IP6Tunnel 207.181.229.138 184.105.253.14
The function attempted to use a name that is reserved for use by another transaction.
(I've used other names for the string - some in quotes - but with the same result.)

C:\>netsh interface ipv6 add address IP6Tunnel 2001:470:1f10:111f::2
The filename, directory name, or volume label syntax is incorrect.
(Which baffles me since this is the suggested syntax for this command.)

C:\>netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:1f10:111f::1
The filename, directory name, or volume label syntax is incorrect.
(Ditto here.)

By all appearances the syntax is correct but I cannot reach a solution to get past the first error, either by using a different string name or putting it in quotes, nothing works. It's the speedbump that's killing the process.

I should add that a network adapter named "Microsoft Direct Point-to-point Adapter" was created but no values can be assigned to it.

I've used that as a string value but to no effect.

Very frustrating, to say the least. Any ideas, folks?
