I have tried to install version update 4.19 several times on different days and it will get to the setup page and that's as far as it will go. What's the problem?
What OS version?
What Anti-Malware?
What do you mean exactly by "to the setup page"
Can you try the slim build (same program only the installer is different in that it doesn't bundle Google software optional install choice) from http://www.piriform.com/ccleaner/builds
