After using the slim build of CCleaner for years, I just downloaded the latest version which is 2.24. I decided to unzip the archive using 7zip and noticed that in the $PLUGINSDIR is a file called system.dll. Is this file installed and if so, where? I don't see it in my current Ccleaner folder and a scan of my OS and programs partitions show system.dll files but those are associated with MS Framework.
When upgrading to a later version, can I:
a - just unzip an exe archive and replace the Ccleaner.exe file, or
b - reinstall the new CCleaner program over the old one, or
c - save my ini file, uninstall the old version and install the new version?
I always seem to use method c.
