How to Block Adobe CS4 From Connecting to the Net

Updated April 17, 2017

Like most software, Adobe Photoshop CS4 occasionally connects to the Internet to find updates and validate that you have a legal copy. An update downloading in the background may slow down your Internet connection. To prevent CS4 from accessing the Internet, block the program through Windows Firewall.

Click "Start," and open "Control Panel."

Select "Windows Firewall," and click "Allow a program or feature through Windows Firewall" from the side menu.

Find Adobe Photoshop CS4 on the list and uncheck the box. Click "Remove" and then "Yes."

Run CS4. If it asks permission to access the Internet, choose "no."

Load "System Preferences" from the "Apple" menu.

Click the "Firewall" tab, and choose "Set access for specific services and applications."

Highlight "Adobe," and click "-" to block CS4 from accessing the Internet.


If you do not allow CS4 to connect to the Internet, you may miss important updates.
