Yes it needs those folders to run properly. At the very least it needs the DATA folder and its sub-folders, and the LOG folder. And I believe that they need to be in the same place as the .exe so that it knows where to find them. Presumably you had deleted the zip after extracting CCleaner64.exe but before running it? (See below). Not quite, there is another way: If I copy/paste only CCleaner64.exe out of the zip to the desktop, but leave the zip where it is, (it was in Downloads) then the first time I double-click CCleaner64.exe on the desktop CCleaner itself extracts the needed folders and sub-folders from the zip to the desktop and then opens. (The zip can then be deleted).

It's actually more accurate to say that deleted files from an internal SSD have little to no chance of being recovered. If it's an extenal SSD connected by USB then there is more chance of recovery. The difference between recovery from HDDs and SSDs basicallly comes down to the TRIM command issued by the computer to SSDs. Unlike a HDD where the file just gets marked as deleted, but the data remains on the drive until overwritten by new data, with a SSD you have to erase the data to empty the 'blocks' of memory so that new data can be written there - and it is the TRIM command that triggers the SSD to perform that 'garbage collection'. A TRIM command usually gets issued by the computer when you delete something - so the data itself gets deleted almost immediately. However because TRIM is an ATA command it cannot be issued through a USB connection. The USB connected SSD will still 'garbage collect' to free up deleted data occasionally, but with no TRIM available from the computer then the data isn't erased immediately, and so may still be recoverable for a while. This short article is a bit old now but explains it well without getting too technical: https://www.datanumen.com/blogs/ssd-vs-hdd-different-chances-recovering-deleted-files/

This is CCleaner Portable open on my laptop,. As you can see it is sat there using 0% CPU. It only uses the CPU when it is actively scanning for junk or doing something else. I also note that mine when loaded but not scanning it is taking 39.9 MB of RAM, whereas yours is only showing 5.7 MB of RAM in use. All of which suggests to me that something is preventing it from loading properly on your machine; for some reason it is 'stuck' during loading and that is why you don't see a user interface. Are you trying to run it as an Admin user or a Standard user? What antivirus are you using, and if it isn't Windows Defender then what version is your AV? Have you been adding extra blocks to your firewalls or hosts file? You say you run it from the desktop, Have you simply extracted the files from the zip onto the desktop? or have you extracted it to somewhere else and then made a shortcut on the desktop? I assume that you are using the portable for your own reasons, but have you considered installing CCleaner?

Are you running it from a USB stick? Where did you download CCleaner portable from? (And where did you get those old versions?) Your screenshot shows it using 24.1% of the CPU and power usage is showing as 'Very High' - which indicates that it is actively doing something , it is not just sat idle in the background.

If you are using Custom Clean then untick 'Session' for the browser. Clearing the browser session logs you out of websites. Also note that some websites still use a cookie to store your login status, if you are using one of those sites then you will need to either: Put that cookie in 'Cookies to keep' in the CCleaner Options. or do a scan in Health Check, click on 'Privacy' and then 'Manage allowed websites' to add the website to the keeplist.

You can download a new CCleaner installer from here: https://www.ccleaner.com/ccleaner/builds Once downloaded just double-click it to install. You will probably need to use your licence key to re-register it again, open CCleaner and go to Options>Licence Key to re-register. Presumably you bought the Premium? There are similar 'builds' pages for Recuva, Speccy, etc.

Check the link in my signature below this post - it explains why some files always come back straight after cleaning, and what you can do to stop some (but not all) of it.

Yes, even in Windows 11 that doesn't have IE, other things (including Edge) use the old IE storage locations. Over the years they have become a convinent place for any application to put temporary files - so even with IE gone they still benefit from a clean out.

It's the cyber security being cautions when faced with something unknown to it. In this case it didn't know CCleaner or what it checks. So it saw CCleaner looking to check what input devices a user had connected (so that it knows what logs may need to be cleaned) - that checking is also the kind of action that a keylogger might do. As the security didn't know just what CCleaner is then to be cautious it would warn of a possible keylogger. It's the nature of cyber security applications to classify activities broadly when outputing warnings to the user or logs. They only have a limited number of option strings that they can output so they pick the nearest one to what they are seeing, to advise the user to look at that possibility. It's a bit like the CCleaner error message saying ' It seems like you are offline' when in fact you are online and it's a server connection that is the problem, CCleaner has just picked it's closest message to display.

I guess that it was a server problem and the faulty server has been fixed then?

As it's happening to more than one user then it sounds as if there is a server issue. Again, the CCleaner Cloud support team would be your contact point to report the problem.

It was noticed a while back that when installing CCleaner for a non-admin user to use then you had to do the 'Run CCleaner' from within the installer as the last step of the install. If you didn't do that then the user permissions would not be set correctly and CCleaner would not work properly (if at all) for the non-admin user. You can try reinstalling CCleaner and making sure you 'Run CCleaner' from within the install. You don't have to uninstall the existing CCleaner. Download an installer from here and simply double click it to reinstall CCleaner: https://www.piriform.com/ccleaner/builds Reinstalling over the existing CCleaner will pick up any cleaning settings and licence key from the existing CCleaner (that's why you don't uninstall it first).

As CCleaner Cloud is a business edition then you have priority support and should contact them using this form: https://support.ccleanercloud.com/hc/en-us/requests/new That's from the help pages that are specific to CCleaner Cloud, you might want to bookmark them: https://support.ccleanercloud.com/hc/en-us

Your first screeshot shows that the file hash was already checked at Virus Total and no problem found. As would be expected with a genuine CCleaner installer.

Assuming that your employee has tried to install the official CCleaner (and not a dodgy repack from somewhere on the web) then I suspect that what you are seeing is normal behaviour when installing CCleaner an a home machine. Support should be able to confirm that for you. However it is probably not behaviour that would be expected, (or allowed), in a business network situation. (There are business versions of CCleaner designed specifically for IT departments to deploy over their networks). Presumably your employers are prohibited from installing their own apps on your business machines. CCleaner home version does require elevated permissions. (Hence the 'skipUAC' option, which although created during install is normally switched off by default). It does scan to see what CPU is running and it does scan for the Windows version in use, so that it knows what/where can safely be cleaned. It does scan for other user accounts, an Admin user using CCleaner Pro can clear junk files from other user accounts. It does scan for installed applications and drivers, it does that in order to know what the user may want to update. It does scan for startup apps, and other scheduled tasks, so that it can put uneeded ones to 'sleep' if the user chooses. It does contact various servers to get up-to-date information, such as new application versions or new driver versions. etc, etc. In short many of the actions that CCleaner does on install, and during use, are not exceptional for an application of the type. Most home use AV/AM applications recognise CCleaner, they know what it is, what actions it takes, and that it's actions are not malware. But if your business cyber security is not expecting CCleaner to be installed on a network endpoint, which it obviously wasn't, then those actions can look typical of what a malware might also do. In those circumstances then most of those actions are are going to trigger your protection application's alarms if a person tries to install a CCleaner home version on your business networked environment. Again, there is always the slight possibility that your employee has acquired an installerr for somewhere on the web that could have been tampered with and repacked. EDIT- I see that your employee says that it was a download from the official site. In which case malware can probably be ruled out and I'd suggest that it's almost certainly simply that your buisness cyber security is not recognising CCleaner home. A case of 'user error', - trying to install something that they shouldn't have on a works computer.

That is just what I was going to say, there is a residue of AVG left that Health Check is seeing and so trying to update. Note that uninstalling an app from within ccleaner just uses the standard Windows uninstaller, nothing more. It doesn't clean anything 'extra' than uninstalling through Windows does. Personally I always use Revo Uninstaller, that runs the standard uninstaller and then scans for leftover files and registry entries retlated to the newly uninstalled app. Like with CCleaner there is a Free version that will do most of what an average user wants, and then a Pro version with extra features for more advanced use. https://www.revouninstaller.com/products/revo-uninstaller-free/ PS. Revo Pro can scan for leftovers of apps that you had uninstalled before getting REVO, using an option called 'Forced Uninstall'. So if you want to use Revo to scan for the AVG leftovers then you will need to download the Pro Trial or buy Revo Pro. Normally I'd say to install Revo Free, reinstall the offending app, then uninstall and scan using Revo Free - but in the case of an AV you might not want to reinstall it. Your choice, but I'd go with the Pro trial and use 'Forced Uninstall'.

Yes CCleaner will clear browser caches and history. Helath check doe s a basic clean of them, but if you use Custome C;ean you have more choice of what does and doesn't get cleared. (Settings in Custom Clean only apply there, they do not change what Health Check will do).

Thanks for the update, it may help other users who have that particular Antivirus app. It is not unusual that Antivirus apps sometimes interfere with the functioning of CCleaner. That is simply because some of the system areas that CCleaner needs to access to perform certatin functions can be regarded as "sensitive". If the AV in question (sometimes just a particular AV definitions update) doesn't know that CCleaner is trusted to access that system location then it will throw a block.

I asked for information that you had NOT provided. (And explained another few issues that you HAD mentioned). You have now provided the requested information. Thank you. Please bear in mind that this is a user forum, all of us here are users. If you want official support then email support@ccleaner.com

There is no difference in functionality between Pro and Pro Plus. The 'Plus' is the number of machines licenced, and also licences Pro for other Piriform softwares on those machines. A CCleaner icon in the hidden section of the system tray indicates that you have 'Smart Cleaning' or 'Automatically update CCeaner' (or both) enabled. So it comes down to the drivers. What drivers are they? What version does CCleaner say is installed and what version does it say is available?

There a very few Mac users on the forum, I don't know why that is. (Maybe they are just less Mac users overall? or maybe they are just not as keen to help others as Windows users are?) The official way to contact CCleaner support is to send them an email; the address is support@ccleaner.com I don't have a Mac, and we don't get that pop-up in CCleaner for Windows, but I suggest that you click the 'Show Me' button and go through it. Usually with things like that then going through the 'show' sets a flag to say that you have done it, which then stops it nagging you.

Health Check was always meant to do a 'default' clean with few options to customise what it cleans. It's intended for those who just want to do a basic clean without having to change any settings themselves. In it's early days it was called 'Quick Clean' and then 'Easy Clean' for a few months. (Before the 'Speed' and 'Security' sections were added and it became Health Check). If you want to change what gets cleaned or not everytime that you run CCleaner then you need to use the more advanced option of Custom Clean. Custom Clean has lists of items that you can tick/untick to specify what gets cleaned or not, that 'sticks' until you change it again. It also allows you to include items not on that list, or exclude particular files that would otherwise get cleaned. Eg. to prevent Custom Clean from emptying the bin you would untick it in the list for Windows-System. Custom Clean would then always leave the bin alone until/unless you tick it again. Note though that Health Check always uses it's own cleaning rules. Ticking/unticking things in Custom Clean does not change what Health Check cleans. (If it did then there would be no point in having both). To set Custom Clean as the default that CCleaner shows you when you open CCleaner go to Options>Settings and change the CCleaner Home screen.

I spotted that there was one of the developers logged on and reading this thread about 2 days before v6.14 came out. He didn't post anything, but is it a coincidence that a few days after that the welcome screen dissappeared again?

The error message shows over 4 Million Terabytes to be recovered, it's hardly surprising that it says there is not sufficient disc space. Look at the 'Last Modified' dates of the files, you have some dated as from 1970 which shows that Windows can't determine their date - and most of the rest have dates in the future. Obviously something wrong there. Look at the fies sizes, some are showing minus values which can happen for files that have no file extension. (it generally indicates a 32bit intiger for a filesize of greater than 2GB). I believe that your problem probably stems from the fact that you say the disk is RAW, had it crashed and you are attempting to get the 'live' files back? A raw disk has no file table, so Windows cannot know what the files on it are are or any details of them. Which will be why Recuva is showing them as just a file number with no extensions, and the crazy dates and filesizes. If you are trying to get the 'live' files back from a crashed drive then the way that I've been able in the past to recover the undeleted files from a HDD that had crashed and become RAW format was: 'Quick Format' the drive with Windows. Recuva can then recognise the drive as one with a valid file table. Use Recuva in Advanced mode to search the newly formatted drive for non-deleted files, and restore them to another drive. As with any attempted recovery there's no guarantees, but that method worked successfully for me - although a very small number of the recovered files were incomplete.

If someting that you use doesn't work like it should work.
