In this tutorial I will show you how to fully activate your PS CS5.1 for free. This technique doesn't include any kind of download such a keygen crack or other kind of shit.
Follow these steps:
1. If you dont have CS5 before, then first Download the Photoshop CS5 trial from Adobe.com.(Note: You will have to make an Adobe Account), and then install it as a trial.
2. Once the download is complete run the setup to begin the install. When you reach the part of the wizard that asks for a serial number use this one below and continue the installation.
3. Then once Photoshop is installed, make sure it is closed and navigate to this directory:
%\WINDOWS\system32\drivers\etc\
4. Locate file named "hosts" and open it using notepad, then paste these lines at the end of the file contents:
127.0.0.1 practivate.adobe.com
127.0.0.1 ereg.adobe.com
127.0.0.1 activate.wip3.adobe.com
127.0.0.1 wip3.adobe.com
127.0.0.1 3dns-3.adobe.com
127.0.0.1 3dns-2.adobe.com
127.0.0.1 adobe-dns.adobe.com
127.0.0.1 adobe-dns-2.adobe.com
127.0.0.1 adobe-dns-3.adobe.com
127.0.0.1 ereg.wip3.adobe.com
127.0.0.1 activate-sea.adobe.com
127.0.0.1 wwis-dubc1-vip60.adobe.com
127.0.0.1 activate-sjc0.adobe.com
It should ask if you want to overwrite or replace the file. Click "Yes" or "Ok".
If you have trouble overwriting, take ownership of your original "hosts" file then try replacing it again. Google this: "how to take ownership of a file".
5. You should now have a completely activated and fully updatable copy of Photoshop CS5.1 Extended.
Note: You will get the occasional pop up asking you to sign in to Adobe Live or some crap like that. Just hit "skip" every time. Don't whine about it. It's worth the thousand bucks you just saved.
