My NIS09 16.7.2.10 installation works OK but I have some questions about it. Here's how I got here.
On Thursday I got the dreaded Symantec Service Framework error. I checked the engine directories and there were two: 16.5.0.135 and 16.7.2.10. The About box still said 16.5.0.135. There were no instructions or hot fixes available then so I uninstalled NIS09, ran the Norton Removal Tool once, and then reinstalled 16.5.0.135. I rebooted between each step. After the installation I ran Live Update until there were no more updates. NIS09 upgraded me to 16.7.2.10 again. It has been working OK since. No error messages for two days. I checked the engine directory and there is only one: 16.7.2.10.
Do I need to take any actions? NIS09 16.7.2.10 works OK, but Symantec withdrew it from production. That doesn't fill me with confidence. I have Vista Home Premium 64bit and IE8.
