Google Chrome could be in the registry as Alan stated and since many setup programs include it as a 3rd party app to also install it will create a registry key even if you refuse to install it.
Also Google Chrome does NOT install into the typical and logical location, instead Google beats to their own drum and has it install into the Application Data folder which is hidden. See here:
Thank you Winapp2.ini, The new distro will be a competitor to Apache server. I'm a Choctaw Indian, so of course my new server distro is called Choctaw server.
When I am done I will do the desktop version as well. I may call it Choctaw TOT ( TOT = Trail of Tears )
Of course some will think that TOT is meaning the child of Choctaw server, which it is as well.
I noticed Google Chrome had appeared in CCleaner, but it was never installed. I did previous searches for Google Chrome in the registry and in C:\ drive folders with no luck. I was about to give up until I found this thread. Yep, found a %localappdata%\Chromium folder. Once deleted, its listing in CCleaner disappeared as well.
