You should only remove the software registration if you have a valid software subscription.
Open your registered IBExpert Developer Studio Edition, open the About window in the Help menu. Click the Remove activation link in the bottom right-hand corner and confirm. A message appears displaying the remove activation string.
Click OK in order to open your email client. If your computer settings do not allow this, you can write a mail to register@ibexpert.biz, and simply paste the clipboard content into the subject heading. If you do not have an email client installed on the machine, then please mail us a screenshot of the Remove Activation string.
