Install MSI from azure file UNC path
If you install an MSI from an Azure file storage SMB you need to map it on a drive. If you do not map it the MSI will result in an MSI error 1619 “This patch package could not be opened. Verify that the patch package exists and that you can access it, or contact the application vendor the verify that this is a valid Windows Installer patch package”. We like to install MSI directly from the UNC path.
