You will need to contact support and tell them what has happened, they should change it for you with no fuss. There is a form you can fill in here: https://support.piriform.com/hc/en-us/requests/new Alternatively you can email your support question to: support@ccleaner.com Give them details of you invoice number. etc. - (Don't put anything like that on this forum where everyone can see it though). I've moved this thread into the 'CCleaner for MAC' forum.

If you are having an install problem (with any software) the first thing I would suspect is that your AntiVirus may be stopping it from installing. Depending on the AV it may let some things install but not others. If you take a look at your AVs logs it should tell you if this is what is happening. That sound just like what would happen if an AV blocked the install. Try pausing/disabling your antivirus and then installing CCleaner. (Don't forget to re-enable your AV afterwards). Or download the 'Slim' installer from here and try installing that. (Some Av's will block the Standard installer but allow the Slim.) https://www.ccleaner.com/ccleaner/builds

I'm not sure about your clipboard issue. On thought is do you have your clipboard synced by any chance? As far as the Temporary Internet Files go have a read of 'Secondly' in this post which is an expalantion of why these temporary files reappear after you have just deleted them:

Yes, I knew what you meant - it's just struck me as funnier to look at it the other way. Maybe they should number next years feature updates as 20-3 and 20-9 (or just stick with 20H1 and 20H2).

Sorry, I was meaning what do the pop-ups say? Knowing what they say we can then work out what is causing them, and advise how you can stop them. The way to stop them will be different depending on just what they are saying.

LOL. - They're only 16 years too late.

More information might help us to help you. What/which pop ups are you seeing that are annoying you?

I'd also suspect that is the probable explanation. It's taking too long to complete a task and so times out with an error, then it immediately tries again and completes sucessfully - which is why the system then runs normally. Of course that still doesn't explain just why it's taking too long and timing out in the first instance. Possibly background tasks loading at startup? Try Settings>Apps>Startup to turn them off?

You can expand and contract it to as many lines as you want to see. Move your cursor to just below it until it turns to a doube-headed arrow, then click and hold down your left mouse button, and drag up or down.

I'm not familiar with that page but I assume you are refering to the blank area on the right? I would try temporarily turning off the browsers ad-blocking feature and see if the content loads then.

You could try Revo uninstaller which can find and remove 'leftovers' that the standard Windows uninstaller missed/left behind. You can download a Free trial of the Pro version, so that you can use the Pro feature 'Forced Uninstall'. (Or buy the Pro if you think you will need the feature again in future). 'Forced Uninstall' lets you use their log database to remove leftovers of stuff you had installed/uninstalled before you even got Revo. Here is the manual page for 'Forced Uninstall': https://www.revouninstaller.com/online-manual/uninstaller/#3.6 You can download the Pro trial here: https://www.revouninstaller.com/products/revo-uninstaller-pro/

Update to this. We are informed by staff that action had been taken against the coupon site in question, and they been instructed to remove the webpage with the missleading advertisment.

I'm not seeing that error either. That may be why I'm not seeing it, I don't use the store. I dont even have a MS account anymore, I did have but deleted it and now use a local account.

Although I was speaking about File Explorer there, normally when you talk about the 'searchbox' it means the white box on the taskbar in Windows (usually next to the Windows key) that you type into to search for things. You can turn it off to save space on your taskbar. In Windows 10 you don't really need it - you can simply click on the windows key and when the start menu pops up start typing the name of what you are looking for and the search will open. It's easier to do than explain - click on the Windows symbol and start typing to see what I mean. (That did stop working for some users in Windows 10 versions 1809 to 1903 but it's been fixed again in 1909). The File Explorer searchbox is a slightly different thing that searches your file system for a particular filename. For most purposes the taskbar/Start Menu search is better for most users and will (usually) find the same things. (It's that "usually" that can some times make a difference.) The search in File Explorer looks like this:

There is now an instruction video in the documentation that shows you what Hazelnut said: The steps shown work for updating from Free to Pro as well. (Putting in a valid license key changes Free to Pro). https://www.ccleaner.com/support/ccleaner#204043844

It can get confusing if you ask the same question twice. You get two lots of answers in two different places, so it's harde for you and others to keep track of what has already been said. I've posted a reply in your other hread so will close this one.

You will need to give more details of just what you did and/or just what you are seeing. For instance are you using Easy Clean or Custom Clean? If you are using Custom Clean than do you have 'Cookies' unticked for that Browser? Do you have any cookies in the 'Cookes to keep' section? Either of those could stop some cookies from being removed.

Indeed not, it just seems all too odd and may well be something else trying to disguise itself. Which is why I suggested that he gets the Malwarebytes removal experts to take a look at his system.

Which CCleaner version are you using? (PS. I don't even have a CC-updates folder in Windows\temp, but that could be a version thing). If you are still in doubt then I would suggest that you join the Malwarebytes forum and ask one of their experts to take a look at your computer for you. It's free and they will have a good look for anything odd/wrong and help you put it right. You don't need to be infected, and you don't need to have a Malwarebytes licence to get their help on the forum. They are happy to check the computer of anyone who ask them to. Start by following the instructions here: https://forums.malwarebytes.com/topic/9573-im-infected-what-do-i-do-now/ To expand on what I said about your screenshot looking odd - There are no Notification, Settings, or Help icons top right, the clouds on the background look different to the normal MB4 background, and my scan results windows don't look like that, although admitted I've yet to have a detection on a MB4 Threat scan so it may just be GUI differences.

I see that you have MB4 Premium, and it says v4.0.4. (Although it looks slightly different from normal there). I've never had Malwarebytes flag the CCleaner installer. I do know that Malwarebytes regularly review their detection methods so I made sure that my MB4 was up to date, there was an update which required a restart of MB4. Then I downloaded a new CCleaner installer and checked - a right-click 'Scan with Mawarebytes' of the ccsetup563.exe reported it as clean. As the link you gave says, FusionCore detections are not malicious, they are PUPs - Potentially Unwanted Programs - specifically bundled software in an installer. In the case of CCleaner that would be the bundled offer in the Standard installer. However I'm not sure that detection is the CCleaner installer at all, the pathname looks odd. To start with the pathname in the detection is all uppercase? ('Windows\Temp\' is usually mixed case). And I'd expext the CCleaner installer to be in your Downloads folder. We can only see the start of the path there, could you tell us the name of the target file at the end of the path? (or even the full path).

To start with that company you link to is not selling anything at all, they are offering money off coupons (or not). In this case if you click on the 'Get Coupon' in your link it doesn't even give you a coupon code, it merely takes you to a Piriform Black Friday offer page, (where you could enter a coupon code - if you had been given one and if it wasn't already at sale price). That Piriform Page clearly states "1 Year subscription..." see below. If a 3rd party coupon website which is nothing to do with Piriform has wrong information then you can hardly blame Piriform for that, complain to the site that has the wrong information.

Apologies, I had missed that 'expired' line on your screenshot of the pop-up. I'll bring it to the attention of the Piriform staff.

Try downloading it from here: https://www.piriform.com/ccleaner/builds (I'd recommend downloading the 'Slim' version as it doesn't include any bundled offers in the installer.) Install that and it will show that it's the free version, don't worry. Go to Options > About and click on 'Upgrade to Pro'. That will bring up a box where you can now enter you name and licence key and click on 'Register'. We suggest that you copy/paste your key in to avoid any typing errors. PS. If that won't download or install then you have a different issue, come back and we'll work out just what's happening.

The Black Friday notice is a totally different thing to the expired license issue: The Black Friday notification is an intended promotion - the expired licence notification was an error. You should only have seen a maximum of 4 Black Friday adverts pop up Aand yes you should have got one yesterday and another today as a reminder that the sale is ending, as it says in your screenshot.. They will stop when the sale ends tomorrow.
