Literally been banging my head against the table, wall and floor over this one. I kept getting the error you can see below when trying to run the SharePoint 2013 prerequisite installer:

There is referenced trying to use a “ServerManagerCMD.exe” in the system32 directory. I looked and could only find a “ServerManager.exe”.
“Well shit”, I thought to myself. Microsoft is bloody amazing and SharePoint is the cherry on top of the cake.
So to fix this, I copied the “ServerManager.exe” file and renamed it to be “ServerManagerCMD.exe”:
And surely enough, after closing the installer and retrying, everything went swimmingly!
