Answered I have had ZA Extreme for years and thought would upgrade to the Next Gen. However, I can't install because ZA says that my OS (8.1 Win) is not supported. I thought there might be a conflict so I uninstalled my Extreme and now I am without any Protection. Removing Extreme did not not help. Any Ideas? ZA said to content tech support to do the upgrade but they have not gotten back to me. Facebook Twitter LinkedIn 0
