CCleaner v6.07 - Incorrect Install Dates at Tools | Uninstall

[lmacri]

My CCleaner Free Portable v6.07 uninstall tool at Tools | Uninstall seems to have incorrect Install Dates for several programs.  For example, CCleaner correctly shows that Belarc Advisor Free v12.0.0 (rel. 11-Nov-2022) was updated from v11.5.0.1 to v12.0.0.0 on my machine on 14-Nov-2022, but:

• 7-Zip was updated from v22.00 to v22.01 (rel. 15-Jul-2022) on 16-Jul-2022, but the Install Date in CCleaner is 10-Nov-2022.
• Intel Driver & Support Assistant was updated from v22.7.44.6 to v22.8.50.7 (rel. 15-Dec-2022) on 17-Dec-2022, but the Install Date in CCleaner is 12-Jan-2023 (Note: the date of 12-Jan-2023 is the same date my Jan 2022 Patch Tuesday updates were installed by Windows Update on my Win 10 Pro v22H2 OS).
   

 

When I go to Control Panel | Programs | Programs and Features the Installed On dates for my current Belarc Advisor Free v12.0.0 (14-Nov-2022), 7-Zip v22.01 (16-Jul-2022) and Intel Driver & Support Assistant v22.8.50.7 (17-Dec-2022) are all correct.

I don't use CCleaner to uninstall programs and rarely go to Tools | Uninstall so I'm not sure if this glitch was present in earlier versions of CCleaner v6.x.  However, I did find several topics for older versions of CCleaner where this same problem was reported - see jdranchman's 14-May-2012 Most Install Dates in Uninstall Tab Just Wrong for one example.

Does anyone know where CCleaner finds the Install Dates for programs (e.g., a registry entry for the last run date or .dll/.exe file property)?

At this point that's a very old bug going back many years and is in many versions of CCleaner.
