Well, to completely uninstall Radiant since it isn't listed in the add/remove list in the control panel, you will have to edit the registry. Otherwise, all the preferences,etc will still be there if you do a new install. First move the entire Mohaa Tools folder (contains Radiant.exe) to the Recycle bin. Then you have to go the your registry (in Windows folder) and delete the keys that deal with Radiant. Make sure they are not Mohaa game keys. Be very careful in the registry as you can do some non-reversible damage to your OS. Maybe there is an easier way to do this but this works. Good luck
