How to Deactivate and Reactivate Adobe Photoshop CS3 to Transfer or Move Activation License Key
Adobe Photoshop CS3 implements an activation system that similar to Windows XP and Windows Vista in order to full unrestricted and unlimited use. By default, Adobe Photoshop CS3 comes with 30 days free trial period. To use Photoshop CS3 beyond 30 days evaluation period, user must activate the software program online or over the phone.
According to license terms, Adobe Photoshop CS3 can only be installed on two computers at the same time. Anymore activation requests will fail and be rejected if user tries to activate Adobe Photoshop CS3 too many times. Luckily, unlike Microsoft, Adobe provides an easy way to deactivate existing installed copy of the Adobe Photoshop CS3 so that the serial number key can be used on another computer, or used to re-activate the same computer after reformatting and reinstalling operating system.
To deactivate Adobe Photoshop CS3, run Adobe Photoshop CS3 program. Then click on Help menu, and select Deactivate. The option to erase my serial number from this computer after deactivation completes is optional, and can be left unchecked. Click on Deactivate button when ready to unactivate the existing copy of Adobe Photoshop CS3.

Once deactivated, the serial number key can be used to activate another copy of Adobe PhotoShop CS3 on another computer, or used to reactivate the same application on current PC after reinstalling.

Recently an employee left, this employee had a activated copy of CS3 on their home machine (as well as at the office). This was overlook prior departure, former-employee has been unresponsive to requests to deactivate. What would be the proper path to have that copy deactivated if the former-employee continues to be unresponsive?

There is no “deactivate” option in CS3 help.
I used to love Photoshop. Now I hate it with the same intensity I hate all the licensing-crippled Adobe cr*p. I’ll just use CS2 and will return CS3 for a refund.
Disgusted,
Steve

If you didn’t deactivate Adobe before uninstall, and it’s asking for you to re-activate, delete the following:
C:\Program Files\Common Files\Adobe\Adobe PCD\cache\cache.db
C:\Documents and Settings/All Users/Application Data/FLEXnet/adobe_00080000.tsf.data
And you can Activate them from scratch again (Including new serial number)
