I've been using ZAISS for the past several years. I've always had problems attempting to upgrade to ver. 7. I spoke to ZA this year and was assured that I'd be able to do it.
I purchased a copy of ZAISS 2008 and installed. I immediately had problems: ZA would not start and my system hung.
So I uninstalled following the manual steps set forth above in the Sticky Post and reinstalled. The result was even worse. My boot time was much longer, ZA did not start and the my system was very, very slow. Worse still I lost my local network connection. The network adapter gave me the "limited or no connectivity" message. When I try to repair it I am told I cannot pull an IP address. Apparently, I've somehow corrupted or lost either my Winscok or my TCP/IP stack.
I've uninstalled ZAISS again and now I'd simply like to be able to restore my network connection.
This is a nightmare.
