I am creating one installer using IA2010. I have added one zip in add files. I want extraction of this zip to begin parallel to installer screen (i.e. when welcome, license agreement etc screens appear). How can i do it?
As far as I know this is not possible as IA is sequential: i.e. you start by the pre-install wizard, and all installation actions are done in the Install task.
If you use an external zip utility, you can run the Execute Command action to unzip it. Just make sure to not check the box "Suspend installation until process completes." If you need a listener for it, you can scan the processes on the system and get thepid that associates with the unzip command. You may need to reference the installer temp dir or extraction folder to get to the zip depending on how you want to access the zip file.
