Installed latest Ccleaner today (6/7/18), and find when I analyze it produces a number of locations to be cleaned, then when I select clean the program closes. I at first thought that it may be that the new version doesn't advise what has been cleaned, then when I analyze again it still shows the same items. I am running the latest version of Kaspersky Internet security.
The previous version of Ccleaner did't have this issue.
