We have Installed "Malwarebytes Discovery and Deployment" tool on on several Windows 2016 Servers at multiple locations but a few of them have this issue. After a network scan , and selecting a machine from the list the "Install" button remains grayed out. After a time the following message will appear on the screen. "The following installers are currently unavailable for deployment: Endpoint Agent Installer and System Prerequisites, Windows XP/2003 Endpoint Agent Installer and System Prerequisites, Would you like to try to download the missing installers again? " Does any one know what causes this or how to correct it?
