Hi, I’ve been using Avast! on my own computer for years, and I'm having no problems with the new v5. But I’ve just upgraded a very old computer for someone else from windows98 to windows2000 (it’s too old, too small, and too slow for XP, so I did an upgrade on the win98, not a clean install). Then I tried to install avast 5. But it refuses to install. It gives an error message saying that the minimum requirement is win2k. So obviously it’s not detecting the upgraded win2k install. Does anyobody have any ideas of how to get around this problem please? I’d really much prefer not to go to another a/v. Much thanks…
