Dear Advanced Installer Support Team,
Let me report an Advanced Installer bug for you.
1. I open our .aip with AI 17.3
2. I navigate to the COM tab where I see my interfaces
3. I right click on an interface and select "New interface" -> new interface is added with a guiid like {00000000-0000-0000-0000-000000000000}. The interface properties are empty yet. IMPORTANT: Do not touch this new interface, just leave it as it is.
4. Click again on Interfaces with right mouse button and again select "New interface" -> "Unexpected error" dialog is displayed. From this point on, you are not able to add more interfaces.
I'm also attaching a screenshot.
Best regards,
Zsolt
