You have Return="ignore" which means "the custom action will run synchronously and the return code will not be checked".
If you want the action to run asynchronously then use Return="asyncNoWait". (I have not done this so I don't know if there are other issues, particularly related to the fact that you are also using 'deferred', which may be elevated, and in a different desktop than you might have intended.) -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Installation-hangs-when-launching-the-installed-application-tp7595184p7595187.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ HPCC Systems Open Source Big Data Platform from LexisNexis Risk Solutions Find What Matters Most in Your Big Data with HPCC Systems Open Source.
