Wireless/TCP/IP version 6 error

TCP/IP version 6 was uninstalled, and I tried reinstalling via the C:\. I typed ipv6, space, intall. I received an error preventing installation. The error: 0x800704b8. I am a novice. I scoured Micrdolt’s site and discovered ipv6 is not supported, and is there for development reasons, so no help there. I checked MSDN, and found the same replies. In any event, I am without connectivity, which, according to Microdolt, should not be a problem, but I do have a problem. Please, if anyone can help me get ipv6 reinstall, I would be most grateful.
Thx,
Al
