…and it does it systematically and reproduceable.
Whenever you use the K-Lite full installer (i.e. K-Lite_Codec_Pack_1900_Standard.exe), then CCleaner will be able to recognize the correct version number of the installed K-Lite pack and reports it correspondingly accurate.
If you have done so (i.e. having V 19.0.0 installed) and a minor update (V 19.0.1) of K-Lite comes along without the full installer but as usual with the update installer (i.e. klcp_update_1901_20250609.exe), then the Software Updater of CCleaner is missreporting it - telling you, that you’re still on 19.0.0 although the version number is correctly entered in the system (as you can see from the screenshots).
CCleaner does that for a while by now but didn’t in the past.
…sorry, I had to delete the uploaded screenshots, being a CCleaner Premium customer seems not to be enough to be allowed to post two screenshots.
