Tried again today to download to Win98 machine. This time, it stalled on the setup file: avpro-3aa-3a8.vpd stopped at 481,236. The virus updates worked fine.
Is there anything that I am doing wrong? Is this NOT supposed to work with Windows 98? Do I NOT need the program updates. Can someone please advise.
Please download the full installer of the Professional or Home version and run it. It will offer you an update to build 938 where this problem should be corrected.
Sorry for the troubles.
i confirm ! it works ! 
It worked for me too. I’m new to the forum but not the program. I’ve never had a problem with the program until now and I’ve been using it for about a year and a half. I came here, read the fix here, tried it and, so far, so good 
Thanks for the help. Sandy01.
