[Ccleaner latest version hangs and wiped out all my thumbnails on my mp4 files]

Thank you , you have been very helpful. It is only because of you that I will buy another license. Great support.

You were correct, but the program (Ccleaner is updating Dropbox now every time I run Health Check), it just keeps updating Dropbox for some odd reason.  If I run cCleaner every night it will update Dropbox to the same version every night. Very odd. I will not run Health Check and use option 2. Thank you.

I'm trying to help you; which I why I need to ask the questions to try and work out what may be happening.

Everyones computer is different, with different setups and different apps, so what affects one may not affect others.
 

One important question there can help narrow down what may be going wrong for you - Are you using Health Check or Custom Clean?

And can you give us a screenshot of when CCleaner 'stops at 85%' we can often a lot from a simple screenshot.

 

AV's change their definitions on a daily basis, sometimes multiple times a day.
It is not unusual (with any software) to suddenly see an issue crop up from multiple users who have nothing in common except that they are using the same AV which has just updated itself.

And just as a PS. 'The latest version' is often missleading, it's best to give the actual version number.
We found this a while back when there was an issue with Trend Micro AV - users of TM were reporting that it was up to date when asked; but there was actually a later version on the TM website that wasn't being offered to them for some reason. When they updated to that later version their problem went away.

I have using CCleaner Pro for 2 years with this same A/V and firewall. I have changed nothing but the update of your program. If you must know I am using the latest version of Eset Internet Security. It has had no bearing on CCleaner before I updated your product, so now I really do not think that's the issue. I tried disconnecting from the internet, and it did not help at all. I have tried uninstalling and reinstalling an older version of CCleaner which did work. So unless you can help me, I really hope you can, my license is coming up for renewal and if I don't have answer, I will certainly not renew. I will check back fior an answer tomorrow, Thank you for your assistance. I always using health check and custom clean. Both. I like to rid my computer of cookies everyday.

After this happened I tried another download and the same thing happened. I use Windows 10 Pro 64 bit ( latest version) all updates installed, when I start the program where it clears the cookies, it gets about 85% done and stops, I waited 15 to 20 minutes for it to finish and it just hangs. This is unacceptable. Either please come out with a download that works or I will be forced to stop recommending your products. I am the owner of a forum that has 500,000 active members. I have recommended your software for the last few years. I hope you can either send me a download that works, or post one.
