Hello Lubert,
I'm afraid I can no longer reproduce the problem. It has been fixed as expected in version 20.4 of Advanced Installer.
Can you please send us more details about the issue you are experiencing? A step-by-step test case could help us to better understand and address your issue. This will enable us to follow the sequence of actions, ensuring a more accurate and efficient resolution.
You can also send us the .AIP (setup project) file or a sample project by email to support at advancedinstaller dot com so we can further test and investigate this.
Best regards,
Liviu
