I am having problems installing the above program. Initially the pc had about 10 virus's which I finally got rid of, I have also ran Ad-aware and spybot to remove another other junk on the hard drive. Windows XP was not running too well so I carried out a repair install. I have tried to install NIS but everytime it seems to install ok but when I click on the desktop icon or any other icon it doesn't do anything. I tried to remove and re-install but it came up with a message about live-update running....which it wasn't and could not run setup. I eventually removed it manually and re-installed it but am again having the same problem. Has anyone come up against this problem before or can you suggest whats going on here. The pc is a Sony Vaio 2.6GHz P4 with 256Mb ram.
