[wix-users] Condition to only Run Custom Actions on Initial Install

[Edwin Castro]

I use the approach described here

https://code.dblock.org/2010/05/11/msi-property-patterns-upgrading-firstinstall-and-maintenance.html

using appropriate property names for my version of wix toolset. The post is
pretty old.

Once you have these properties available you can just use FirstInstall in
the condition which is easy to read and understand.
