Disable Adobe CS4 Activation Check

// May 22nd, 2009 // Tips & Tricks

You can disable Adobe CS4 Activation Check by editing your windows “hosts” file.

For that- open C:\WINDOWS\system32\drivers\etc\hosts with notepad and paste the following at the end:

127.0.0.1 activate.adobe.com
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

PS: This is not for cracking your pirated Adobe CS4. Please buy original product, and if you don’t have that much money you can go for alternative tools like GIMP for Photoshop, Aptana for Dreamweaver etc.

Update: We bought licenced Adobe Photoshop CS4 & Dreamweaver CS4... Hurrayy!!!

    Hi Fread,
    The “hosts” file has no extension. So when saving, you have remove .txt and select file type as “All files”.

    Disconnect from the internet and close any CS4 programs you have open.

    if you are attempting to execute this on a windows 7 machine, you may need to provide administrator priv. a few times. You may work around this by copying the hosts file to your desktop, opening it with notepad, editing, saving it as file type “all files.” It may still save as a .txt, but I’ll get to that in a moment.

    Copy it back to the \drivers\etc folder and allow with administrator privileges. If the other hosts file remains, delete it and follow these steps

    Then, bring down the Organize tab, navigate to

    folder and search options > view
    and uncheck “hide extensions for known file types”

    rename hosts.txt as hosts
    no file extension.

    Again, provide administrator privileges to complete this action.
