I installed 2011 Internet Security but only have the product #. I do not have an activation number. I visited support and it scanned my computer and said it found no Norton product. I am running Norton software with Win 7(just installed) but again no activation #. I have an account and I have visited it. The product has not been registered. I put the product on with internet on. I guess I should just start over. Any suggestions for such a simple question. thanks.
