I downloaded/installed 5.4 just few minutes ago. Was attempting to get but it still does not open. When the blue box prompt comes up to allow changes to computer, when yes is clicked I get error starting program “CCleaner requires Windows 7 or later” I have Windows 10. Now what should I do? I have spent most of afternoon and now evening with issues trying? I also rechecked Trend micro and updated just now. Still not working. Please help me
