@James RIchter: seems that that work-around is to disable the video downloader:

Thanks for the sleuthing to narrow it down for us. This is with our developers now to investigate a fix.

@APMichael: FYI https://www.ccleaner.com/news/release-announcements/2020/07/21/ccleaner-v5697865 Please let us know if that does the trick.

Note that if you would like to disable the built-in notifications when a new version of CCleaner is released, you can configure this through Options > Updates and uncheck the "Show me notifications for these updates" flag if you don't want to be prompted when a new release comes out. However, once you get too far out of date you will get additional warnings anyway (about once a week). This will generally kick in once you hit 4-8 versions out of date, depending on what compatibility changes were made in those releases.

To clarify, is your concern relating to the fact that some features show a little padlock on them? Or does this relate to the notifications to free users on out-of-date versions that there is a new free update to download for free?

If you are referring to HealthCheck - some CCleaner customers love it, and some prefer the original interface. As a great philosopher* once wrote: "¿Por qué no los dos?": https://support.piriform.com/hc/en-us/articles/360028349191-I-m-using-Health-Check-but-prefer-CCleaner-s-original-way-of-cleaning-How-can-I-set-that-as-my-default-cleaning-method- * May have actually been a small child in a taco commercial

For paying customers approaching their renewal date there are periodic offers to renew/upgrade at a special price. It would have got a little noisier yesterday and today since the current "2 years for the price of one" offer is ending in a few hours. If you "no thanks"ed the last chance message today then you should not hear anything again for a while.

Indeed, out of over 80M successful installations with the improved offer layout since March @nukecad seems to be the only person to have actually captured this in the wild - and we've been unable to replicate it. So if anyone else get a screen that looks like the one that he posted above - we'd love to hear from you. For everyone else, if you get an AV offer in the installer (not the "if" - offers are not always made at all) it should be rather hard to miss:

That would be a concern. Were you having this issues before or after you had a the Technician Edition installed? As the Technician Edition is not generally publicly available (it's a special paid licence for IT technicians doing breakfix on multiple computers) I would be concerned if, as you were trying to find a solution, you may have downloaded something from some other site that may or may not be the genuine article. Either way, with the various install attempts, is there anything left behind in the C:\Program Files\CCleaner directory that may be causing an obstruction? Also: Did you have any problems with older versions of CCleaner prior to 5.61? Have you trying reinstalling any of those older versions recently? Windows 8 was never as popular as Windows 7, but we do have a few million Windows 8 and 8.1 users actively using CCleaner 5.61 and up

@Dusty54: I checked and can see that you raised a tickets as a free user over the weekend. You followed up a second ticket on Tuesday, and a third separate ticket 20 hours ago, also as a free user. On each occasion you would have been notified that (emphasis added): Since none of those tickets were from your account email, response would be delayed, as you were advised. Also the first one was over the weekend, and our customer support desk currently only operates on weekdays at the moment. You raised a 4th ticket 17 hours ago from a different email address where you did provide your order number and I note that you received a response within 40 minutes - which seems like a pretty reasonable response time for the priority queue. As @nukecad points out, as per https://support.piriform.com/hc/en-us/articles/360039530092-Will-I-lose-any-time-on-my-subscription-if-I-take-an-offer-to-renew-early- it can take up to 15 days for the system to automatically extend licences. Looking now I can see your licence ending YVVF running until 25 July 2021 - which sounds right. You can confirm this at https://www.ccleaner.com/support/license-lookup.

This. The suspending active tabs function is specifically to stop inactive tabs grinding away in the background devouring RAM, CPU cycles and battery as other browsers are often wont to do. And this is probably the key "is it a bug or a feature" question - especially if the pages are of the type that are constantly dynamically refreshing themselves, live streams, etc. @SSL: specific cases to point the devs at would be very handy, please.

Everyone be nice. For context, a community site for a software utility with a mammoth user base, such as this one, can be quite a magnet for "SEO consultants" and the mods spend an outsize percentage of their time swatting spammers for dietary supplements, etc. As "teaser" posts often end up being a prelude to advertising, they get understandably nervous when solution posts lack details. Also it's nice to share the details for the benefit of others So welcome!

... if you have an active paid support licence for Recuva. Otherwise, we can try some things on here. Have you tried right-clicking the installer file and "run as administrator"?

The slim installer was created because as of CCleaner 3.01, ESET objected to the Chrome toolbar offer that was present in the full installer - although this was removed back in version 5.58. For a couple of versions, the slim installer was needed to successfully install on Windows XP and Vista - but was 5.64.7577 was the last CCleaner version to support those operating systems. The only remaining use-case for the slim installer is for compatibility with some screenreader software for the visually impaired. For anyone else it is essentially a placebo - but not a very good one, since any problems with the configuration of your computer (eg: blocking the CCleaner messaging server) that would stop the full installer from running would also have an adverse impact on the operation of CCleaner as well. If you are in a country like the USA where the privacy laws are rather lax, compared to where we are in Europe, then I can understand your skepticism. But, you don't have to take our word for it. Feel free to lodge a GDPR request for a copy of all data we have on you if you like - but I have probably spoiled the surprise on what you will see in my previous post You have been told incorrectly - unless you regard any hit of any sort of an web server (such as viewing a page on a website) as IP collection. This is a real-time inspection with nothing retained. It is also a legal requirement for export compliance - while I am sure that folks in the impacted countries would benefit from CCleaner, as a distributor of free software we really don't have the budget to pay out the fines for violations of the Global Terrorism Sanctions Regulations. There's no secret that Avast owns Piriform. When any company buys another one there are efficiency gains made - as such we share their drinks fridge, they use our ping-pong table, and we piggy-back off a corner of their CDN server to save on bandwidth costs. Lots of companies buy and sell other companies like trading cards - Unilever owns Marmite, Ben&Jerry's ice cream, and three nominally rival brands of tea, for example. The mining company BHP owned Fosters brewing for a while - and I can assure you there was no coal secretly added to the beer.

There would appear to be some misconceptions in this thread. For example: There has been some form of telemetry collected since December 2010, starting with licence activation counts. Despite persistent urban myths to the contrary, this has actually been actually wound back significantly after Avast showed up on the scene. As @nukecad pointed out, that didn't make any difference, by the way. The in-product telemetry data can be "blocked" more gracefully, and without breaking anything, by simply opting out through Options > Privacy in CCleaner 5.46 or higher. Since the telemetry only collects an aggregated tally count of how many users use what features, the best real world analogy would be voting. No-one knows who you vote for in an election or referendum - and if you choose not to vote then you have chosen to have your opinion ignored in favour of those who do. CCleaner does not collect any personal information on our users, except for some minimal information required to maintain licence subscriptions for our paying customers. And we have never sold any customer data. (All other factors aside, this would only be of interest to our competitors, and we are generally disinclined to give them this sort of assistance.) We have no use for your personal data, and under the various privacy laws that we are subject to, if we did collect and store it (y'know, just in case it might be useful later for something) then we are legally obliged to spend a lot of time and money to maintain it and look after it forever. With a user base larger than the population of most countries, that would be exceedingly tedious and burdensome - so we don't collect it at all. It would also look rather odd for a performance and privacy tool to do so. For more information on all of this, you can refer to the CCleaner data fact sheet: https://www.ccleaner.com/about/data-factsheet Under law you can, of course, request a copy of all of the data that CCleaner holds on you if you'd like to check it. To save you some time though: If you are a paid user then pretty much all of your information can be found here: https://www.ccleaner.com/support/license-lookup If you are a free user then this is actually a pretty comprehensive view: https://this-page-intentionally-left-blank.org/ Exactly this. If you are blocking the web service components that CCleaner needs to operate (in the mistaken belief that you need to do so to block the telemetry that you have already switched off) then, yeah, you are going to have problems. The primary use-cases for a firewall or hosts file block of CCleaner are: A user with a pirated serial key who doesn't want a NACK signal back from the licence server. A user in North Korea trying to circumvent the trade sanctions geo-blocking. ... neither scenario we are particularly motivated to assist. TL;DR: don't be this guy

Are you sure? The latest version at the time of writing is 4.22.1.

@Yllek: CCleaner for Mac keys also start with a C. If what you have was labelled as "CCleaner Professional for Mac" specifically on your receipt then you should be fine. If it only says "CCleaner Professional" (without "Plus" or "Mac") then contact support (support@ccleaner.com) requesting an exchange.

Is this blank screen the first one you see? Or the second one after the one with the licence agreement, customise link, etc? Was this downloaded from CCleaner.com or a third party website? Have you had any difficulties in the past with previous versions of CCleaner? Have you customised your hosts files or your firewall software to block your computer from reaching any of our web servers?

CCleaner will peacefully co-exist with any correctly maintained antivirus software (ie: kept up-to-date by both the developer and the user). However multiple always-on antivirus software will generally not peacefully co-exist with each other. Sounds like Norton and PC Matic may be too busy fighting over whose turn it is to check CCleaner to let you open it. Try switching one off (and ensuring the other is up to date)

Depends on whether this is a CCleaner Professional licence key (starts with a "C") or CCleaner Professional Plus licence key (starts with a "P"). CCleaner Professional Plus keys will work on both Windows and Mac. CCleaner Professional keys are for Windows or Mac and one won't work on the other.

Note that this is a public forum - so for specific assistance with your account you are best off contacting CCleaner customer support (support@ccleaner.com) with requests relating to you subscription. There are a couple of different ways to cancel your subscription - via the product or via the cleverbridge purchase confirmation, or their pre-billing notification email. If you cancel through us then we notify Cleverbridge that your auto-extension should be cancelled, and it shows up on your account status if you click through from Licence Information in CCleaner. However, for some reason if you cancel through Cleverbridge, they don't always notify us. That means that while the autoextension is still really cancelled (since Cleverbridge controls that) the billing may still show up as active in our view of your account status. This is naturally unsettling and something that we are working on fixing with Cleverbridge at the moment since, amongst other things, it generates a lot of tickets to our customer support demanding that we cancel something that has actually been cancelled. In your case I was able to look you up on Cleverbridge and can see that you received a pre-billing reminder from Cleverbridge on 16 May, were billed 30 May, and cancelled future billing extensions on 29th June (approximately 12 hours ago). I can confirm with 100% certainty that your billing status is, at the time of writing, indeed deactivated as you wish it to be.

You might form the impression that in its early years, Piriform may not have thought through its licensing model properly, and that the notion of restricting paying users to 12 months of updates while free users can update their product indefinitely was probably quite daft, or at the very least awkward. And you would be right. Which was why we went to the cleaner subscription model for new sales in 2018 and after. The term limit for updates on those home-user licences sold up to the end 2017 was 12 months, as specified in the software licence. An argument could be made that the 12 month period should have been explicitly mentioned in the product description. A counter argument could be made that at that time, the notion of a lifetime of free updates would have been so unusual that no reasonable person would assume that a company would gift such a thing to them unless it was a headline in the sales pitch (cf: my previous Microsoft Word example). However, ultimately these are both positions of little practical interest, given Piriform's ongoing desire to ensure that legacy licence holders have an ongoing experience and functionality that is, at the very least, no worse than that of free users - which means that legacy licences can currently still be manually updated. At this point, the future direction is most likely to be that this will continue, and that the paid features that were present in 2018 (eg: automatic browser cleaning, scheduled clean, multi-user profile cleaning) will remain enabled but that the web-service features introduced in 2019 and after (currently Software Updater, and the Speed and Security sections of Health Check) would be withdrawn. Do you mean according to the EULA, or as per your experience? You are getting an error message when you attempt to register your CCleaner licence key? Sounds like the 3 year CCleaner Professional licence that was briefly available for sale from December 2018 to November 2019? Having been sold post January 2018, that would be why the clearer receipting.

The built-in "new version" notifications that look like this ... ... can be controlled under Options > Updates > Product Updates > Show me notifications ... ... although if you leave it for too long (usually 3-6 months) between updates, you will still be poked by the "out of date" pop-ups. As per the screenshot above, the automatic product updates is a paid feature, and unlocked with CCleaner Professional:

@Prids: This looks like an odd one. Which Windows 10 build were you using on the affected machine? And which which build version on the two that are still ticking along fine? Are there any other notable differences between your different computers in terms of the other software installed - particularly AV, firewall or any other "always on" system utilities? And are you able to provide an extract of the relevant section of the dump file for us to review please?

Common solution to "0x6" problems: Right-click CCleaner > click Properties Open the Compatibility tab Check "Run this program as an administrator" Click Apply > OK
