[No response from the support team]

To be honest at the moment  support in general to users from emails queries, and from admin responses on forum, is a bit of a disgrace.

We moderators find it difficult to get any answers to questions we have too.

Does the built-in Win 11  System Information tool work okay for you?

 What happens if you run the 32bit version of Speccy? (It's in the installation folder)

Are you running it as admin?

No, I did not find its icon appeared in system tray but just running as a process in task manager.

Click on the Details tab instead of Processes. 

Then right-click on it  in that listand select Properties.

Anything that catches your eye?

[Problem using the App on Xiaomi A2 lite. Is it a bug?]

I am sorry to say that CCleaner support via email or the  webpage is sadly very lacking at the moment. We have no idea why.

We do our best  here on forum, but we are just ordinary users like you.

[I accidentally used wrong email for subscription.]

Never a good idea to post any email addresses on an open forum.

Please contact CCleaner by email instead.

[CCleaner Community Forums needs Dark Mode]

@Hmm

Dark mode is already available for the forum (I use it)

Scroll to the very bottom of the page under the icons for Facebook etc and click on Theme.

The dark mode is not perfect but for me it's 100% better than the blazing white with pale fonts.

[why does free trial not work]

What happens when you try to use it?

What operating system?

Where did you download it from?

Have you use CCleaner before?

[program is corrupted, will not open, will not uninstall ... totally hung up]

 Try looking in taskmanager and ending task of anything related to CCleaner.

Also go offline before running the uninstaller.

What operating system are you running ?

[Opera One(version: 100.0.4815.76)]

I used it years ago before it went to the 'dark side' 

I liked it, but then switched to Vivaldi.

I don't see the file myself but I understand why it bugs you to have it. Does it still appear if you RUN CCleaner with no internet connection?

Why did Piriform change things in the first place ? Why did Piriform feel the need to put in an extra tick... I mean it's pointless.

I suggest you read an ongoing thread about this here (3 pages) which may give you some ideas.
