Ladies and Gentlemen, be of good cheer!
I have found a way around the bustage and I credit TJeske for pointing me in the right direction. I am pleased to report that as a result of what I am about to share that I have an HE tunnel that gives me 10/10 (
https://test-ipv6.com) and 20/20 (
http://ipv6-test.com) using the HE tunnel script for Win 10.
Here we go:
From where one can find it, obtain the .iso for v1709 and extract it to the folder of your choice. Within it, search in Windows Explorer for nettun.inf. You will find several files with either that name or the name within the file name: (Caveat; you may have to Take Ownership of the files and the folders in which they go for the copy transfer to work.)
nettun.inf - copied to these folders: Windows\INF and Windows\WinSxS\amd64_nettun.inf_31b...(etc)
nettun.inf_loc - copied to these folders: Windows\System32\Driver Store\en-us and Windows\WinSxS\amd64_nettun.inf.resources_31b...(etc)
amd64_nettun.inf.resources_31bf3856ad364e35_10.0.16299.15_en-us_7612c139e588cebb - copied to Windows\WinSxS\Manifests
Now, do a search for tunnel.sys. You will find:
tunnel.sys - copied to these folders: Windows\System32\drivers and Windows\WinSxS\amd64_microsoft-windows-tunnel_31b...(etc)
tunnel.sys.mui - copied to these folders: Windows\System32\drivers\en-US and Windows\WinSxS\amd64_microsoft-windows-tunnel.resources_31b...(etc)
Now, run the tunnel config script from HE, check the results with ipconfig /all, and you should have your v6v4tunnel tunnel in place.
I must caution, however, that I did run into a few snags while going through all this. You may well have the Microsoft Direct Point-to-point "Adapater" (yeah, that's what it says) but it has a yellow flag by it due to it not recognizing the driver as being digitally signed. This is the sucky part. Test the driver by drilling down to Windows\INF to nettun.inf, right click it, click Install and see what happens. You might get a warning about a third-party driver signature issue in which case you'll have to do this:
Reboot by holding the Shift key while clicking Restart, choose Troubleshoot, then Advanced Options, then Startup Settings. When the reboot comes around, you'll have a menu from which to choose. Pick Option 7 Disable Driver Signature Enforcement and let the reboot continue to its end. Drill back down to Windows\INF nettun.inf, right-click it, click Install, and this time you'll likely get a warning with the option to "continue anyway". Choose that, and you're good.
If for some reason things get botched and you want to delete the "adapater", go to Device Manager, click View, show Hidden Devices, right click on the "adapater" and Uninstall. Re-run your HE config script and THIS time things should be good to go.
Having typed all this, I have possibly left out some more caveats with all the trial-and-error I went though before I succeeded, so if there are any snags you hit along the way, I'll gladly try to walk/talk you through a solution.
Good luck, folks, and happy IPv6ing!
