Required Execution Level for the msi, not only the exe
Is it possible to set the Required Execution Level to Administrator for the msi as well? I know it is possible for setup.exe and I get the UAC window once user starts the exe installer. If not possible for msi, how does it get around it? I would think UAC would cause some problems when it is executing some UAC related stuff?
Required Execution Level applies to manifests which are used in .exe files, so have no bearing for .msi files. There is a setting in General Information > Summary Information Stream "Require Administrative Privileges" which indicates whether the execute sequence needs elevation, but it does not work the same way. It elevates by also running as a system service.
One option if you really need to enforce things would be to set a Launch Condition based on the AdminUser property in a project that sets MSIUSEREALADMINDETECTION to 1. In general I would not recommend this; instead relevant custom actions should be set to run deferred in system context.
