Recently I have noticed recent updates to CCleaner result in the Tools | Uninstall list no longer showing the Size of the Program for programs that V5.88 did show the size of. Is this intentional? This information was useful to me; was this intentional?
An example of this is 7Zip. Under CC 5.88 the size is shown; on any later version, including 6.03, the size is missing.
That's quite curious, as my understanding was that this data was retrieved from the same location of the registry as the Windows Apps panel (or Programs & Features) retrieved it from, so there should be no mismatch (either between the Windows panel or different versions).
I'm able to see install size for 7-Zip in the Windows Apps panel, though, and not in CCleaner 6.03. (I don't currently have an older version installed, but from what you describe, I'm sure it would show there.)
I'll let our development team know about this so we can see if any of the changes made in recent versions had an impact on this. Thanks for reporting this!
I see the same thing in the current CCleaner v6.07 at Tools | Uninstall. Please see the images I posted in my 23-Jan-2023 topic CCleaner v6.07 - Incorrect Install Dates at Tools | Uninstall that show that the Size column of the majority of programs (including 7-Zip) are blank. Of my ~ 95 programs listed at Tools | Uninstall less than 15 have a Size listed.
However, the majority of my 48 installed programs at Control Panel | Programs | Programs and Features have a Size listed, including my current 7-Zip v22.01.
Part of the discrepancy in the number of installed programs is likely due to the fact that CCleaner's Tools | Uninstall also lists my ~ 45 Universal Windows Platform (UWP) apps listed at Settings | Apps | Apps and Features (e.g., Calculator, Weather, Feedback Hub, etc.) that are available from the Microsoft Store, but that shouldn't really matter. The "Windows Apps" tab of my <a href="https://www.revouninstaller.com/products/revo-uninstaller-free/" rel="external nofollow">Revo Uninstaller Free</a> utility lists the Size of all these UWP apps.
