Customize uninstall of software

[EF-Peeush]

Hi,

I've created a basic MSI installer for the software.
Now we want to customize uninstall such that process should ask if user want to remove a specific file from the "Program Data" folder and remove the file based on user selection and then continue with the uninstall process.

Kindly suggest how can we do the above customization in uninstall process.

Thanks in advance

Custom Action-> Create a YesNo dialog and on YES DeleteFile( FullFilePath ) nad handle if error.

Open the Help file and search for DeleteFile and there's an example of how to use it.
