Hi, no, it is located in E:\ , I never had it in Download folder. Yes, I downloaded 22.214.171.124 from toolslib site, the app work well; only since 126.96.36.199 the "remove" botton has no effects. I can update it by simply manually deleting it, but this remove botton shows that there is a problem. Its is strange. PS. only in this moment I received the notification email of your replies.
