[wix-users] Find if upgrade / Install inside Custom Action

[Ven H]

Thank you. I am sorry for being naive but I am not able to understand how
to achieve what I am looking for. All I want is, during running of MSI, how
can I find out if it is a fresh install or an upgrade from within a custom
action.

Regards,
Venkatesh
