Is it possible to install only a Custom Action if the statement is true based of Launch condition? Let's say i put a launch condition to see if a registry key exist & if it's exist than install only a Custom Action not the whole MSI?

Is this possible if Yes can someone please guide me what tables to look for or if i can somehow put a condition in my Custom Action.. Thanks in advance

Your condition would go into the CONDITION column of the InstallExecuteSequence table based on the results of AppSearch

In IS go to system search create a new search (right click and select add) -> Select Registry entry -> enter the registry location that your looking for -> Define a property
In Launch Condition table add the property with the value you are looking for. (eg:DONETFOUND="4.0") then specify the description for the error message if the condition not met.
