Ccleaner not cleaning Adobe Reader DC files

I just reinstalled both Ccleaner and Adobe Reader DC due to a computer issue. What I have noticed is Ccleaner is not cleaning the Adobe Reader PDF files, that I looked at, even though the Adobe Reader clean is enabled in Ccleaner. Any suggestions? Thanks

CCLEANER portable build 5.92.9652 is not deleting Adobe Reader DC history.

It does not show any history if a scan is run on just the Adobe Reader DC item.

I have tried unchecking and rechecking the checkbox.

Any other ideas please?

CCleaner v 6.08.10255 is still not deleting history in Adobe Acrobat Reader v2022.003.20314.

Can this be added? When will it be added?

This could be because the 64-bit version, which Adobe now prefers, uses a different registry key. The cleaning rule would have to be adjusted accordingly.

RegKeyX=HKCU\Software\Adobe\Adobe Acrobat\DC\AVGeneral\cRecentFiles
RegKeyX=HKCU\Software\Adobe\Adobe Acrobat\DC\AVGeneral\cRecentFolders

Thanks. Confirmed that is where I find the references to the Adobe files that are not being deleted.

It would be neat if a "Custom registry keys" feature could also be added like the "Custom files and folders" feature. And a "Registry key" option added to the Options -> Include dialog, like the Options -> Exclude dialog has.

How does the Adobe key update and the above feature suggestions get added to the developers' task list?

Unfortunately, it often takes a lot of patience until a change makes it into CCleaner.

You could help yourself with a winapp2.ini file:

The cleanup rule would then look like this:

[Adobe Reader DC *]
LangSecRef=3021
Detect=HKLM\SOFTWARE\Adobe\Adobe Acrobat\DC
Default=True
RegKey1=HKCU\Software\Adobe\Adobe Acrobat\DC\AVGeneral\cRecentFiles
RegKey2=HKCU\Software\Adobe\Adobe Acrobat\DC\AVGeneral\cRecentFolders

Thanks for the effort to reply so promptly and comprehensively. That worked perfectly and can be applied to a few other things too - much appreciated.

Any chance you'd know the keys or files for the Windows 11 Start -> Recommended section at the bottom? There are two categories of data that CCleaner does not clean up:

  1. The history files (amongst others, there are OneNote files that I'd like to clean up when CCleaner is run)
  2. The recommended apps

Thanks

You're welcome. I'm still using Windows 10, so unfortunately I haven't dealt with Windows 11 that intensively yet. Sorry.
