ccleaner won't open after downloading and installing Version 5.65 update.
I have an up to date Windows 10 Pro, 64 installed and it's working good with other programs and also CCleaner Version 5.64.
Issue is that after downloading the CCleaner installation file, (Free Version), and install it with the install wizard as per normal, when I try to open CCleaner, it will not start.
There is the little Microsoft blue spinning 'doughnut' as is normal just before the program starts, (always there, is normal), but the 'doughnut' disappears, (again is normal immediately before CCleaner starts). However, the doughnut goes away and CCleaner (new V 5.65), does not start at all. There is no error code either.
I ended up doing a disaster recovery from a backup disk to the computer to get the old version, (v 5.64) back. I did this twice. The first time about a week ago and the second time today.
What antivirus do you use? Currently users of a specific antivirus have been having this sane trouble. One that is fixed by the latest version of that antivirus.
I always check for updates first thing of the day when I first turn on PC. Trend always automatically updates when checking for updates when there are any updates.

Also Trend is up to date.

Actually, it is trend that has the problem. When you update tm from within it stays as trend micro 2018/2019 to update for sure download from
I did have to to whitelist ccleaner in trend micro.
I already did have the latest TrendMicro installed, but I reinstalled it anyway and still had the issue until after white-listing CCleaner in TrendMicro.

Hi folks - I downloaded and am using Ccleaner 5.65 on a Win10 Pro system running McAfee Enterprise antivirus (managed by my company) and am having this same issue. Ccleaner was working fine until this latest update. I just tried running it and see the following in Windows Event Viewer:
Faulting application name: CCleaner64.exe, version: 5.65.0.7632, time stamp: 0x5e7256e6

At any rate, seems to me that the issue is not limited to TrendMicro. Any input here would be appreciated.

Do you have access to the whitelist function of McAfee enterprise? I assume you have ypur tech administrator's permission to run ccleaner?
There were a couple of reports very soon after 5.65 was released that McAfee also blocking it, but the issue went away after a day or two as McAfee definitions updated for home users.
McAfee Enterprise may not have had the same update?, or your IT may not have applied the update yet?
@nukecad - thanks and good to know. I work for a large company and not sure what updates have been applied. I'm going to install on one of my other computers to see if it exhibits the same issue. Next step after that might be to our IT support org which is always fun. Thanks again
As Nergal pointed out - Do you have permission from your employers/IT to install and use CCleaner?
Most employment contracts prohibit the installation/use of any third party software by employees unless IT approve it first.
It's not unknown for one employees to inadvertently install malware that then infects a whole organisation.
There is usually a list of approved software, and a process to get anything else you want/need approved.
It is often a disciplinary, or even sackable, breach to install software without permission.
