NSClient++ Help (#1) - upgrading nagios windows client (#847) - Message List

Hi guys,

I'm trying to upgrade from 3.8 to the latest 3.9 windows client and it doesn't seems to work. I would have assume that by using msiexec /i NSClient++-0.3.9-Win32.msi /qn should work. But when I did just msiexec /i NSClient++-0.3.9-Win32.msi, with the GUI up, it came up with options to : upgrade, repair or remove.

I've also tried using msiexec /fa NSClient++-0.3.9-Win32.msi, and this ended up breaking it.

please help. Cheers
