    Question [SOLVED] Validation failed. Missing a necessary root certificate -> Reinstall OS

    I got an error during my fresh installation.

    OS: Windows Vista Home Premium 32-bit SP2
    Computer: HP Compaq CQ40-325TU Notebook PC
    Memory: 3GB

    I downloaded ZoneAlarm Free Firewall (without anti virus) version 12.0.121.000 from ZoneAlarm official website. I tried to install but error occurred:

    [Configuring ZoneAlarm Firewall... 18%
    Validation failed for C:\Program Files\CheckPoint\ZoneAlarm\vsinit.dll. You probably are missing a necessary root certificate.]

    I tried to uninstall but cannot. Then I perform HP system (factory) recovery again. I updated the Windows to SP2, same problem occurred also.

    My computer time zone and date/time settings are correct. I also installed Internet Explorer 9 and .NET Framework 3.5 on my computer also.

    Anyone can help? Thanks.
