[wix-users] Run custom action only during modify

[Vladimir Kolobkov]

Hello Satya,

Not sure that i know how to do it the right way.
But you can test features of your msi for current state, and if at least
one is already installed then you are probably in the change/modify or
uninstall.
Not sure about repear or upgrade or patch but it can be tested :).

For example:
<Custom Action="*%Action you need to run%*" Before="*%any action%*
"><![CDATA[(&*%FTR_Name%* = 3 AND !*%FTR_Name%* <> 3) AND UILevel < 4 AND
NOT (REMOVE ~= "ALL")]]></Custom>
As i remember:
- this action runs on silent mode( UILevel < 4 )
- not for uninstall( NOT (REMOVE ~= "ALL") )
- if feature "FTR_Name" action is INSTALLSTATE_LOCAL(&*%FTR_Name%* = 3)
- and if feature "FTR_Name" current state is not INSTALLSTATE_LOCAL(!
*%FTR_Name%* <> 3)

probably you need to check current state only and not the action.
