Renewed my license 2 weeks ago. Worked for a week or so now fails to launch on boot, license key renewal message, etc. It will not take the license key that I was provided after renewing. I don’t need this hassle but need some help. I can’t believe Piriform doesn’t have a toll free number for support just email and wait.
g'day Chris and welcome.
below is a link to double check your license key and one to raise a support ticket but it sounds like you may have already;
use this link to get the key resent to your email; https://www.piriform.com/support/license-lookup
or a support ticket can be raised from here; <a href="https://piriform.zendesk.com/hc/en-us/requests/new" rel="external nofollow">https://piriform.zendesk.com/hc/en-us/requests/new</a>
make sure you copy/paste the key in, as O (for Oscar), 0 (zero), I (uppercase i) & l (lowercase L) are easy to mix up.
if no luck on that front, also try;
uninstall your current version first.
then go into the Program Files folder for CC and delete its contents
(keep the .ini file if you have customised settings)
download the latest build from here; <span><a href="https://www.piriform.com/ccleaner/builds" rel="external nofollow">https://www.piriform.com/ccleaner/builds</a></span> (or use FileHippo for previous versions)
reboot the PC then install CC from your downloaded file.
to convert this Free version to the Pro, go to Options > About and enter your license key.</p>
