I have been struggling with getting my ZA (free) install upgaded from 7.0.337 to 7.0.408 the last couple of days with no luck. I've tried clean uninstalls (by adding "/clean /rmlicense" to the uninstall script). Every time, my system either with hangs at startup or I have all sorts of problems after the reboot which enables ZA 408. By "problems" I mean that my system performance tanks... completely. Nearly every process stops responding for up to a minute, even the desktop interface. Eventually, if I wait long enough, my clicks and such registers and the machine limps along until I actually try to start another process or anything else.
All this is done with my WAN unplugged, since I'm uber-paranoid and always disconnect before doing a ZA update. As soon as I reconnect the internet, the systems hangs for good. Only my mouse cursor works at that point. Even the clock stops updating. I wind up goind into safe mode to uninstall 408, and the machine comes up fine the next time. I've tried clean uninstalls of 337 and 408, but nothing lets me install 408 and have it operational once I reboot.
OK, one thing did... when I allowed 408 to install the trial ZA-ISS, it rebooted and everything worked fine... until I reconnected my internet connection. Then the only thing which worked was the mouse cursor. I couldn't even click on desktop icons... and tried waiting several minutes for a response. I've tried most of these processes with and without McAffee disabled with no change.
I just read a couple things about installing in safe mode and/or re-downloading the installer from Explorer. I'm willing to give those ideas a shot, but if anyone can give me an idea as to _why_ they might work I'd really appreciate it. There have been a few releases over the years which just "haven't worked" for me, and this is looking like one of them. However, I'm really hoping to get 408 installed because I was planning on upgrading to a licenced copy of ZA-ISS or ZA-Pro soon. That doesn't seem advised if I can't get 408 working though.
FYI, I'm running:
McAfee VirusScan Enterprise 8.0 (engine 5200)
For as reliable as ZA has been over the years, this is driving me nuts because of the time I've already spent tinkering. I think the reason I'm getting obsessed over 408 is because I've finally committed to a licensed version... now I probably couldn't install it. Without sounding pathetic... Help please! :-)
