I am taking over for a technician who was doing an Office 365 deployment. He was getting fired and decided to be spiteful and uninstall AD-FS 2.0. Now I am tasked with trying to install AD-FS 2.0 and get hit with "Setup has detected that a previous version is installed on the computer" and must be removed through server manager.
I want to know is that the only option that I have?
