The key holds a list of values representing applications along with trigger dates, after which you'll get asked again to install Chrome. Other ones I see there include Irfanview and Avast. I tested it by changing the date for "Piriform Ltd" to a past date, and then re-installing CCleaner. This time I got asked about Chrome. So, one mystery solved, I guess. The only other thing I wonder about is the claim (by the same guy I mentioned in my first post) that CCleaner's offer to install Chrome could not be declined, that Chrome got installed no matter what you did. That was not my experience, but maybe there was a defective installer in the past. I did find one other similar report after doing a Google search, so maybe there's a grain of truth to the story, even if there's more to it than just that.

You're right, although the "no ask" period appears to be about 6 months, not forever. Thanks for pointing this out. In case anyone wonders, the registry key in 32-bit Windows is: [HKEY_LOCAL_MACHINE\SOFTWARE\Google\No Chrome Offer Until]

Regular installer, not Slim. I usually download it from the /download page, not /builds, but I just tried the full installer from your link now. I didn't get any Chrome or toolbar offer. Maybe you won't get the offer if you've declined it in the past? Maybe if I were to uninstall my current version and install it from scratch I'd see it?

Hmmm... I use the free version, downloaded from http://www.piriform.com/ccleaner/download . I periodically download the latest version directly from Piriform and install it over my existing one, and I don't recall seeing the Chrome offer. I have the latest (3.27) installed now, but I just downloaded it again and installed it over itself, and I don't get any Crome offer. Is it possible that only the installation files that come from Filehippo and Download.com carry the offer?

In another forum, someone is claiming that version 3.19 offered to install Google Chrome during installation. I'm skeptical of that claim - I know that more recent versions do not include that offer, I don't remember it ever doing so. I've been using the free version of CCleaner since long before 3.19 and I I've never had Chrome on this computer. I always download CCleaner directly from the Piriform site. Is there any possibility that this guy could be right?
