Well, I finally got vsn 9 up & running. After reading above advice I thought I'd try again. This time couldn't get vsn 9 to install, Either live update or offline update. Kept hanging at about 88% looking for location of NUP115.msi file. So decided to uninstall vsn 8 & do clean install of vsn 9. But couldn't uninstall vsn 8 - so had to do a manual uninstall, safe mode, etc. Then installed vsn 9 which went fine. However once installed - still couldn't access web. Went into protocol filtering and had to manually add the client files. They were listed in the add dialog window - but had to manually add them. Then all worked well. I think vsn 9 has some sort of firewall incorporated as I hadn't had this in earlier updates. After getting it up & running on desktop, decided to install on laptop. Here installation went smoothly and worked right off the bat. Didn't have to get into protocol filter. Picked up clients automatically. So as was earlier suggested might have some basic conflict with my desktop computer. Could be so as it's configured as a dual boot system still running DOS6.2 & WinXP with System Commander at boot up. Still don't care for the UI of vsn 9. Thought vsn 8 had a cleaner look. Anyway all is well. Thanks to all for help.
