I'm not so sure why this happens. Can you please send us the .AIP (project file) and a verbose log
of the installation to support at advancedinstaller dot com
so we can investigate them?
If you cannot share with us your project file, then you can try to isolate the behavior in a buildable sample (.aip + its referenced files) which we can build and test on our side.
Also, please try to give us a step by step test case too.
All the best,
