ArcGIS Desktop 10.5.1 was pushed out to all users last night. The update will overwrite your old version of the software.
Please check to see that you've got the new version on your machine (assuming you had the old version, of course).
A quick check to make sure that your start menu looks like the attached phote (w/"SDE 10.5.1" in the name). That will show that the GHE Windows Powershell script has also installed along with the software.
If you DON'T have the latest version please put in a ServiceNow ticket to get it re-installed.
