Manually Registering Zend Studio


There are situations when a manual registration of Zend Studio is needed, i.e. a registration procedure that bypasses the standard Registration Dialog.

The two most common reasons are:

  • There is a problem in the installation or in the system that prevents the Registration Dialog from working correctly.
  • Installation automation - for example, an unattended installation on developers' workstations in a Windows domain.



The registration status is checked on every Zend Studio startup based on the validity of the license key. This license key is stored in plain text form in a file located in the user's home directory. To register Zend Studio manually, simply copy the license key from My Account and paste it into the corresponding file:

Windows   –   %USERPROFILE%\.ZendStudio\0_0

Linux / OS X   –   ~/.ZendStudio/0_0


The file name 0_0 is used for Zend Studio 10.5 and newer. Previously file names 9_0 and 10_0 were used – correspondingly for Zend Studio versions 9.x and 10.x.
