In 2010 ESRI took the advice of the group and created an Uninstall Utility for ArcGIS Desktop. This allowed you one application that when run displayed all the currently installed ArcGIS Software that was older than the version of the utility (e.g., Uninstall Utility 10.3 showed all 10.2 and older software that was installed on the machine). The user could then click uninstall all to get rid of the conflicting/old software or select them one at a time from the list to uninstall. This Utility was removed with the deployment of ArcGIS Desktop 10.4.
Request is to release this utility for 10.4.1 and 10.5 software.
