is it possible to set a property in Deferred custom action.If so please suggest me the way ?
I had similar dilemma few weeks back. And this is what was told to me by seniors.
Deferred Custom action cannot directly modify installer properties. But there is an workaround: you can use immediate custom action to set the property.Also you could use CustomActionData to store property value and then use it in C# or VB.net Custom Actions.
I think this Link might help you.
