This latest update is much slower than previous versions. Question 1: Is that to be expected? Question 2: If so, what is the best way to revert to the previous version? Question 3: If not, can I uninstall and reinstall without losing my license? THANKS.
G'day Bob and welcome,
I can't answer Q1, too subjective. all depends on what they have changed and what you are cleaning.
Q2, previous versions can be found on FileHippo (just use care on that site and make sure you are clicking the correct Download buttons)
Q3, you can always plug back in your license key via the Options, About menu, then the blue License button.
Also, get the latest from here; http://www.piriform.com/ccleaner/builds
they did an emergency update to fix a Mozilla issue.
