CCleaner Help Requests

Need help installing or using CCleaner on your PC? Be sure to check the Frequently Asked Questions collection from the Piriform support website. If you need information on your paid CCleaner licences, expiry dates, registration information and download links you can get that directly from https://www.ccleaner.com/support/license-lookup. Can't find the answer in the FAQ files? Maybe it has already been asked and answered here - or start your own thread.
IMPORTANT: Users are reporting that recent versions of CCleaner do not open when their AV is out of date. If your CCleaner 5.65 has stopped working and you are using an old version of Trend Micro antivirus protection, you will need to update your Trend Micro from here https://esupport.trendmicro.com/en-us/home/index.aspx.
