Morning all, I've been using CCleaner and other Uninstallers for that matter. Being and old DOSser I find under : C:\Program Files a bunch of Directories (<DIR>), some empty, some not which I try to get rid of with DELETE ..only to get the message : "access denied ". This is annoying and to me it's the proof that when uninstalling, some remnants were left behind and CCleaner won't find/delete them. Is there a cure for this. Thanks and greetings from Antwerp Lorias
