Below are the MSI deliverables you may use for automated deployment.
Warning: exe and msi installers use different installation paths, so upgrading exe to msi or the other way around will not keep your users' enrollments. We recommend that you keep the same installation method (EXE or MSI) for deploying upgrades.
