Hi Arto,
The shortcuts are created during the "InstallExecuteSequence" -> "CreateShortcuts" standard action. You can show it by using the "Show Standard Action" button on the toolbar of the "Custom Actions" page. Therefore, your custom action should be scheduled under "InstallExecuteSequence" -> "CreateShortcuts".
Also, only
Immediate custom actions have access to installer properties. If the custom action runs as deferred, it will not be able to change the property you are using.
If your custom action is configured this way and the problem persists, please send us the AIP (project) file you are using to
support at advancedinstaller dot com so we can investigate it.
Regards,
Cosmin
