Query: Usual Norton Installation Problems

I've continued with Norton only because of, hopefully, the easy installation from each version. But, as with the upgrade from 2004 to 2005 it failed. I then uninstalled 2005 (as it failed), and then I could not uninstall 2004 ("Please uninstall newer version"). I cannot remember how I fixed it. I now have the same problem going from 2005 to 2006. So although I uninstalled 2006, 2005 no longer works and will not uninstall. As I write I have no longer any anti-virus software as nothing works. I will have to google again a solution. This is most definitely the last Norton product I purchase. Sorry, but this software is totally sub-par. Mr Norton should be ashamed of standing behind this product. I sincerely recommend that you do not buy this.
