How to Deactivate Photoshop

Adobe gives you the tools to deactivate a Photoshop installation.

Developed by Adobe Systems and included in its Creative Suite of design products, Photoshop is a graphics creation application that allows users to edit bitmap images by changing document sizes and color modes, adjusting levels, applying filters and effects, adding text and shapes, and more. To help prevent piracy, Adobe limits the number of installations for which a single Photoshop license can be used. If you have reached this limit and need to install Photoshop on another machine, deactivate one of your existing installations through the program's Help menu.

Instructions

1. Open Adobe Photoshop.

2. Click "Help" in the top menu bar and select "Deactivate."

3. Check the box labeled "Erase my serial number from this computer after deactivation completes" if you want Photoshop to do so.

4. Click "Deactivate" to run the deactivation process. This process cannot be canceled.
