How to interact with basic MSI in silent mode?

Hi,

I need to implement a basic MSI with silent installation – and there will be an external wrapper above the MSI which will display the GUI.
Since that wrapper will show all the UI, it should communicate & retrieve some information from the MSI during the installation.
So my questions are:
1. How can I report the installation progress from the MSI to the wrapper? (The wrapper should show the progress bar itself…)
I can write a custom action, but how to obtain the progress itself from the MSI?
2. How can I report errors like “no disk space”, “locked files”, etc to the wrapper?

Thanks!

You might search the help for "external UI handler" for information. (InstallScript MSI projects are one example of this approach.)
