Thanks for quick response John,

Yes, the appx was signed using a self signed certificate. I will try it by using a derived certificate. The sample attached in the GIT repo do not work as well?

samples: https://github.com/Microsoft/msix-packaging/tree/master/preview/Win7Msix/Tests

On Windows 7, What will be the difference between the apps installed using MSIX or MSI route. Will the security/container benefits of MSIX still apply?

We will look to get the sample corrected.

For MSIX down-level, it will not offer containerization prior to 1709. It will do the integrity checks and validate signing. It will be MSI like since there is no filesystem or registry virtualization, but should offer a better uninstall experience. The goal of the down-level MSIX installer is to allow developers to create and distribute one package and help them to accelerate MSIX for their apps.

John.
