@fredzillab: "Trackers" in Heath Check include multiple things that may reveal your history of online activity, but are not quite as alarming as they might sound. See here for more information https://support.piriform.com/hc/en-us/articles/360041169212-Why-are-there-so-many-trackers-found-in-Health-Check-Should-I-be-worried-

@Richard Hatfield: It can be easy to lose track of things if you have licences attached to multiple email addresses - but you can always pull up your information (licence key, expiry date, etc) for a specific email address from https://www.ccleaner.com/support/license-lookup If you have accumulated multiple licence keys that still have time left on them then the good folks at support@ccleaner.com would be happy to merge and consolidate them for you - be sure to refer to "merge licence keys" in the subject line. Our US support team shift is just about to knock off for the weekend though, so they probably won't be able to get to it until Monday though.

@Anthony Parsons: thanks for confirming. As mentioned above, we've hoping to make that entry field a little more robust in the next release, but in the meantime your case has helped contribute to an updated FAQ file https://support.piriform.com/hc/en-us/articles/204043844--Problems-activating-or-registering-CCleaner-Professional

I think I may have found a potential data-entry trap with the new format of the licence key input box. To accommodate different-length keys, the box no longer limits the number of characters that are entered, so it would be possible when copying and pasting to accidentally include some trailing or leading whitespace, eg: The developers are already looking at a way to make this field more robust to that sort of thing, but in the meantime, could I get you to check that no stray spaces crept in when you were copy-pasting?

... except that we don't. Tracking and data collection is the "price of free software" for the likes of Facebook and Google, whose core business is selling advertising space in the most sophisticated way possible - "if you're not the customer then you're the product", etc, etc. At CCleaner, however, our core business is selling our own software. We've always had a sideline in flogging other things during the installation process - but that has never been sophisticated Since we're not an advertising company, user data is for us the equivalent of nuclear waste. We can't use it; under the various privacy laws that we are subject to, if we store it then are legally obliged to spend a lot of time and money to maintain it and look after it forever; and if it leaks into the environment then we are in serious trouble. The most elegant solution to such a problem to simply not collect it in the first place. So are you to believe that we give away millions of copies of CCleaner every month solely from a sense of altruism? Of course not. To use the current trendy jargon for something that has been around for decades, it's a "Freemium" distribution model (https://en.wikipedia.org/wiki/Freemium). While on one hand, only a relatively small percentage of free users will consider the extra benefits of the paid version worth paying for, but on the other we don't have to spend a fortune selling through retail stores or OEM preloads on laptops - where for every $1 spent by the customer, at best 50c (but more usually 15c or less) makes it back to the software developer. On a related topic, I am now off for a quick walk around my garden to try and get my step count up on the "free-to-play" mobile game Pokemon Go ... while attempting to resist the temptation to shell out another 99c to Niantic for in-game goodies

This is now a two-step process, first the licence key: .. and then your name: Changing this to two screens in 5.66 was done for future compatibility to changes in the licence system, but also to help provide more specific guidance with registration issues as to whether the problem is that the user needs to correct the entry of their licence key or their name.

While we know that people love to tinker with settings and configurations, please note that blocking bits of CCleaner - either by firewall or by host file entries - may have undesired effects. Proceed at your own risk.

Automatic updates for 12 months (or 24, if you buy 2 years). If you have remembered to register your licence key, of course

Recuva will restore what it can, but if a photo comes back that has been chewed up by being partially overwritten then some image viewers will simply report it as corrupted and refuse to attempt to open it. Some success has been reported in the past from trying more fault-tolerant viewers such as IrfanView https://support.piriform.com/hc/en-us/articles/209176787-How-can-I-recover-photos-

Although we don't advertise it as such, you can use the CCleaner Professional Plus (where the licence key starts with a "P") to install and register CCleaner (but not Defraggler, Recuva or Speccy) on a Mac. But at this point in time the Android licence is a separate purchase. https://support.piriform.com/hc/en-us/articles/360028350711-How-many-computers-can-I-install-CCleaner-Professional-Plus-on-

... which is why we have always had (and always will have) a free version of CCleaner available BTW, there is no "mark as answered", as such, on here. But for some hot topics there will be a promoted answer and a "solved" tag added to help people coming to the site at later date to more easily find answers.

... although, if I may add, there were some specific instances of people claiming to have Windows 7 issues which actually turned out to be attempting to install or run CCleaner in Windows XP emulation mode.

BTW: That ideas portal gets results

@OmerWow: And due to popular demand, it was recently added in CCleaner 5.66

Well naturally it would be lovely if they did - but, in the interests of transparency, I would make the observation that of all of the CCleaner Professional licence keys created prior to 2018, less than 3% have been cancelled for any reason (including refunds, licence abuse, etc) since licence revocation started back in 2012. One might reasonably conclude that with a cumulative rate of less than 3%, there is probably not some form of nefarious cash grab afoot.

There was a major problem specific to version 5.33 ... but that was 33 releases ago. Versions prior to 5.46 should not be used on any recent build of Windows 10, and Windows 10 will actively block you from using anything prior to version 5.36. Given that one of the reasons that CCleaner releases new versions so often is to keep up to date with configuration changes in the various software that it cleans, we always recommend staying up to date with the latest version (currently 5.66), and certainly no more than a few releases behind the latest (https://www.ccleaner.com/ccleaner/version-history)

... specifically, did you type the number "1" instead of the capital letter "i", etc? As Nergal said, copy-pasting instead of manually transcribing tends to solve most registration problems.

Minor bugfix for CCleaner Professional trial users. Should be an update to the release notes shortly.

No - actually it comes from when a computer registers a licence key. It is pretty fundamental to any form of licence management to be able to know how many computers paid software has been installed on. This is not exactly a new development for Piriform - the very first entry in the activation table is dated 2010-11-30 at around 3pm GMT. Its primary use is for customer service - letting customers know if they have purchased a licence but haven't installed it yet, or troubleshooting if a customer has accidentally made duplicate purchases so we can help them figure out which one they are actually using. But given the rate at which some businesses seem to like to pirate software - licence enforcement is also a thing, and has been since the beginning. Number of times registered is pretty much it in terms of anything tied to an account. But a more comprehensive answer to that question is available from inside the Options > Privacy section of the CCleaner product itself. For those who may have missed the link, here it is: https://www.ccleaner.com/about/data-factsheet.

Are you able to see which process initiated those calls?

I did try to recommend that you contact support so that you could get answer in private - but if you would like a public answer specific to your case: you didn't mistype your key. Your key was disabled for licence abuse. To reiterate the previous points for all - if you bought a home use "version-based" licence prior to 2018 and are using on the number of PCs that you bought it for then no-one has "switched anything off". However, if you bought a 1 PC licence and are using it on a half dozen home PCs, have deployed it across your company network, have published it on your blog for anyone to use, or have tried to resell the same key to hundreds of people on eBay - you are inevitably going to have a bad time. Anyone who may have made a genuine mistake is encouraged to contact support to see what they can do for you (rather than outing yourself in public).

@dottoss @murdog: The answer you seek is right there in what murdog quoted.

ESET Update: Multiple reports from users that ESET/NOD32 has fixed their false positive flagging, although as per @Spartan to ensure you get the fix ASAP you may need to "right click on the ESET icon and choose update so it will update to the latest definitions then restart your computer. Then it won't be detected". To be confirmed, but a similar refresh of your AV should also fix most other major AVs as well. As a side note, we have also had a report from someone who rang ESET customer service that they were told (incorrectly) that 5.66 was blocked due to PUA. I can only imagine that was a 1st level support engineer reading from an old script, since that would refer to the offer of the Chrome toolbar extension that was present in the installer for many years, but that we removed 11 months ago with version 5.58 (see https://www.ccleaner.com/ccleaner/version-history)

... with additional custom modifications for ad blocking, anti-fingerprinting, reduced RAM usage and longer battery life.

@jayzus: 99% of the time that would be due to mistyping the licence information when registering a copy of CCleaner. Keys purchased prior to 2017 were only disabled in the event of a refund, trade-in or licence abuse. If you believe that none of those apply to you then please contact support.
