Cannot install, Avast 5 thinks I'm running Windows server

Avast Free Antivirus / Premium Security
1

My very old but still working computer OS is Windows 2000 Workstation SP4, and was using Avast 4 PRO until recently when I purchased a 3-computer Avast 5 licence and tried to upgrade this machine.

Installation says my computer is Windows Server and does not meet minimum requirements of Win2k or higher. This machine in actual fact is not Windows Server, it’s Win2k SP4 and has been for many years!

The first time I tried to install Avast 5, Avast PRO 4 was still happily running. Installation seemed to go OK but when I rebooted I got the blue screen of death (BSOD). I used safe mode to uninstall Avast 5 so now I am back to where I started except I have no AV protection at all.

When I try to install Avast 5 I get “Your operating system does not meet the minimum requirements. You can install avast! only on Windows 2000 or higher. It cannot be installed on Windows Server.”

Here is the log:

Please make sure you have the Update Rollup 1 installed (it’s required for avast! 5):

Yes that was the problem, the rollup had not been installed, which I now have done. I reinstalled Avast 5 (AIS) and everything seemed to go fine. Except there was no network connectivity at all :(. I tried turning off the firewall and turning off other stuff, it seemed to make no difference, there was no network connectivity whatsoever, I could not even ping the router.

So then I uninstalled Avast 5 again, and my network connectivity came back. :slight_smile:

I think I will forget about using Avast 5 on my old Win2k machine, and just use the AV protection provided by the ISP :P. On my XP machine Avast 5 AIS seems to be OK.

Did you reboot after installation before testing connectivity?

Yes, rebooted a couple of times to see if that would solve the problem, it did not.
