I don't get it, Praises get negative and critics get positive votes??
There's something wrong here. Must be gamers.
What's the point of putting out a positive point out there when all you're gonna get is is shot down in flames!

Free version and this. What's the difference please?

When I run setup.exe, all I get is the "successfully activated" window but no program anywhere. ( I got the email with the key sent to me but nowhere to put it.) I ran it again with the virus security program disabled temporarily but no change. Am I missing something?

Thanks to Glary company and giveawayoftheday for the program. Glary was giving a lot of useful programs (not only their own producing, but other programmers also) during the years for every person who wanted. Their programs are useful and "easy to use". So, may everything will be OK with them, and thanks to them for their hard work.
And givawayoftheday too.

The installation failed until I turned off Avast! All went smoothly after that. NB: I got a pop-up saying my copy was successfully registered, but it wasn't. When I checked, the license was for a previous version from GAOTD, which was due to expire in a month.

I have a permanent free version that does all I need it to do for my PC. This one gives us a license for one year. My version has been working well for my PC for several years, catching and helping to clean any unwanted files or programs out.
If you are someone that needs a pro version, go for this. I see no need for me to get this, as my version is doing everything I ask it to do.

I havent used this yet, but it has decent reviews on the 'net, so I downloaded it. It does have quite a few steps to go through to finally get the download going, and then you have to figure out how to use your key, (on the interface, choose manage license, then click switch license and put the code it emailed you- check your spam folder for the email, that's where mine was).

I have been using this for years the program is updated regularly

The Glarysoft trim program has never been bad, it has some parts that are better not used. Mostly, cleaning up is more than sufficient. Glarysoft automatically adapts to the language of the computer. Has found three upgrading of programs that are not immediately necessary. You can always use the 30 -day trial version.

It's an excellent piece of kit.

Works flawlessly, have used it for years, and always happy to see GAOTD offer it. Has many useful tools for most people, the defragment tool was my go-to for many years, till I switched to an SSD.
