My computer is a Mac OS Mojave 10.14.6. I have used the older version of ccleaner and all was fine. Upgraded to the new one and at first it loaded and when I ran it, it quit at 25%. Tech support said to uninstall and reinstall. When I slid the icon to my applications folder, it duplicated my applications folder many times AND there were no CCleaner files installed. Tech support said there would be someone more experienced getting in touch with me. It has been over a week. The tech support is just about non existent!
At this point it is useless to me and I just want my money back
