Verified method to bust CS4 activating silently.
Internet can be connected, no Firewall, no activation (no one is asked) and... that works.
1. Modify this file:
C:\WINDOWS\system32\drivers\etc\hosts (open it with notepad)
2. Add this to the end of it:
3. Run the keygen. Remember if you enter this serial number in any application, it will work for all Adobe CS4 applications.
Now Adobe thinks it's activated and don't try to phone home in order to verify the serial n°.
To be sure it's working well, I put back the old hosts file (without 127.0.0.1 activate.adobe.com). I Launched Encore, and boum, a Nag screen telling me my serial isn't registered in the database... I closed everything, put back my new hosts file. And I'm having fun now.
