Hello Martin and welcome to our forums,
Sure, I would be glad to assist you here.
If possible, could you please forward me the following resources:
- a copy of the AIP file
- the name of the app so I can download it from the store
- a test-case to test this
by email at support at advancedinstaller dot com so we can run some tests and further investigate this on our end?
Best regards,
Catalin
