Hi Matthias,
We strive to always improve Advanced Installer and I'm wondering what is your scenario regarding the support for custom action? Can you please provide some insight?
To execute a .vbs or .js code you can use the predefined
Execute inline script code custom action. If your custom action is a .DLL (C++ or C#), then you can use the predefined
Call function from attached native DLL custom action. For PowerShell, you can use the predefined
Run Windows PowerShell Script custom action.
Best regards,
Dan
