I had the same issue when I ran the InstallRolesAndFeatures.ps1 with PowerShell. My solution was to go and manually enable all the features from Turn Windows features on or off as they are presented here in this Server Roles and Features article. After I enabled all features, everything worked like charm.
Hi there, I have started installing Orchestrator. Wondering where do you get the InstallRolesAndFeatures.ps1 - I don’t see a clear description of where to get it from? Any help would be much appreciated.
