block ccleaner in hosts
Once you have Downloaded the trial Installer DISCONNECT FROM THE INTERNET
When your Internet is Turned Off, Install Ccleaner.
Start the Program
Enter Following Information when Prompted. License Key : PM3A-3VPT-3IV6-Q5KK-4U4F, Name : Does not matter ( enter your Super secret internet Pseudonym or type in random stuff)
Block " 127.0.0.1 license.piriform.com " in your Host File.
To do so you need to find your Host file . Usually in C:\Windows\System32\drivers\etc
Run your text Edit Program of choice, in my case Notepad++ as an Admin.
Now write that "127.0.0.1 license.piriform.com" at the bottom of the file. ( without "" )
Make sure it Saves!
Run Ccleaner
Once you are in the main Ccleaner window and it asks you to perform a Healthcheck , you can Turn on the Internet Again.
