Hi
XP was released in 2001, At the time IPv6 was not a part of any mainstream
system.
E.g. Can you easily install new electronics gadgetry on a Car circa 2001.
Yes, if you are an avid self doer. No if you just go to the Dealer.

This worked like a charm for me, too!
Anders, you're a Scandinavian genius!
Now why hasn't Microsoft put something like this in their Knowledge Base?
I've been looking high & low for 3 days trying to track this down; thank
God
I just happened to notice that I couldn't install TCP/IP 6 as well, but my
main concern was the Peer-to-Peer component in Windows Networking.
Many, many thanks!

Hi, I had the same problem. I'm running Win XP (Pro) SP2. I fixed it
by enter the following command in the command prompt:
esentutl /p %windir%\security\Database\secedit.sdb
After that, installation of TCP/IP Version 6 worked fine.
Hope it will help someone,
Anders
