Hi,
The attached ZIP file contains a CUB file (darice.cub) that comes with Windows 10 SDK and it can be used to fully validate your package. Just download and extract the file to a desired location, then open your project, go to "File > Settings > Package Validation", check the "Enable ICE validation for MSI packages" option, use the "Browse" option and select the extracted CUB file (see image below). After this, a full package validation will be applied on your package at build-time.
Best regards,
Eusebiu
