Update failure

I have windows 7 and the 5.65 (Professional) has auto-downloaded but will not launch

I don't know if anyone else has had this problem, but after installing/updating to v5.65, ccleaner stopped working. I plan to reinstall, but any suggestion would be appreciated.

Need more information than stopped working. What happened exactly? Which OS are you using? Did the install of the update finish? At what point does it "stop"? after press clean? during analysis? loading?

The more information you give the more we can help.

I am having the exact same problem, free version 5.65. Try to execute from icon of start menu nothing at all happens, just won't execute. Tried uninstall, reinstall, reboot. Nothing worked. Windows 10 pro 64 & up to date.

I have a paid version of ccleaner pro, installed on a Win10 system. The install seemed to have finished normal, no indication that it didn't. The program itself fails to load/start. No messages, even checked task manager and nothing, no processes or services were started. Been a user for years, never had an issue before this.

Found the problem, but not the fix. Ccleaner is being blocked from starting by my Trend Micro Maximum Security antivirus software, Version:16.0.1302.

yes, you found the fix: Use a different AV

I use McAfee Endpoint security and have the same issue after upgrade. "A problem caused the program to stop working correctly. Please close the program.". Windows 10, CCleaner Pro, 64bit version. Upon launching the program I get:

Downloaded free version 5.65 and have the same problem. I also have Trend Micro Antivirus+

Had to re-install version 5.64.

I have a paid version of CCleaner Business Edition on a windows 7 with ESET NOD 32 antivirus. The home screen shows version

5.64.7613 and it says update 5.65.7632 is available. So, I've ckd it to update and it shows the progress, that it has updated, then I get another update notice for the same one. Apparently it is in some kind of update loop. Something isn't working right. The program itself seems to run fine, but the update isn't installing properly. Is there some

kind of log file I need to delete or something?

I downloaded the latest update and could not open ccleaner pro after the download was complete numerous attempts from various menus still didn't work

I uninstalled and reinstalled ccleaner pro twice it wont open I uninstalled it again and that's where I am now I am running a Dell Latitude with widows 10. Help

I now find that ccleanerpro will open and work as long as I turn my security (Trend Micro) off. as soon as I turn it back on I cant open ccleanerpro

Sounds like you need to Whitelist ccleaner in trend micro (see trend micro on how to do that because i don't know).

Mine Will Not Launch Either I also have win 7

Are either or both of you using Trend Micro?

Ihave the same problem (windows 10. CCleaner pro. paid) have to turn off ransomewear protection on Malwarebytes ,

this only started happening with new update

Fixed the problem with Trend Micro - Just add ccleaner to the exception list. Not sure I like doing that, but it works

Checked my malwarebytes-didn't help. Still won't install the update. Just looping, looping ...

Malwarebytes can be known for this problem from time to time with various softwares.

The ransomware protection component is especially prone to doing it, it seems a bit too keen at times.

You might want to report it over there: https://forums.malwarebytes.com/

There is obviously an issue for some users and at this stage we are trying to work out if it's a bug or simply a case of the AV's needing to update their definitions for the new CCeaner version.

It often happens with a new version of any software that AVs take a couple of days (or even weeks) to update their definitions and stop blocking it.


It depends on just how the particular AVs detection engine works, which is why some are more prone to doing it than others.

Trend Security/Trend Micro are confirmed to be blocking v5.65 at the moment, and McAfee is also reported as doing so.

I'm getting the attached screen error with v5.65, rolled back to v5.64 and was OK. (WIN 10 64-bit)
