Enable WMI Windows Installer provider To install software on Windows machines using the Install Windows App activity, enable WMI Windows Installer provider on all target machines. Before you begin It is recommended that the MID Server, the target machine, and the installer source machine be on the same Active Directory domain. However, if these computers are on separate domains, those domains must have a trust relationship established between them. If the installer path is a UNC file sharing machine, the Active Directory account of the target computer must be trusted for delegation. For instructions on this configuration, see the posting on the community for installing and uninstalling Windows applications.
