CCleaner Installer has not functioned for me for over a year now! in CCleaner Help Requests Posted February 16 2 minutes ago, Dave CCleaner said: That installation option screen seems to be missing some graphical elements, which is odd. I don't think I have seen that before. It should look more like this: The second snapshot with the blank screen - was that what you saw after you clicked on install? If so then note that CCleaner loads some of the UI content from a server, and a blank screen on this second step is usually a sign that you have got CCleaner's network access blocked (either via a firewall rule or some 0.0.0.0ing in the hosts file). A sort-of-work-around for network-related blockages in the installer is to use the "slim build" instead (https://www.ccleaner.com/ccleaner/builds) although it is important to note that will simply defer the problem from installation to operation if the issue does indeed relate to connectivity. Okay thankyou so much man! That tells me a lot that I didn't realise I even needed to know. Appreciate you going through the images and noticing it wasn't right. I will make a firewall exception for the installer if I can and get back to you if that fixes the problem.
