Before you can save your work with the non-USB Key version of Isadora, you need to activate an Isadora license that works with Isadora 3 and/or 4.

When you purchase your license, you’ll receive an email with your eight-digit License ID and eight-character alphanumeric License Activation Password.


Once you have your license information, you can activate your Isadora license by taking the following steps while your computer is connected to the internet:

  1. Launch Isadora 3 or 4.
  2. From the menu, choose Isadora > Help > Activate….
  3. Put License ID and License Activation Password into the fields of the resulting dialog box.
  4. Click “Activate Online”


Once the information is verified, your license will be active on your computer and you will be able to save your work.

If you are using the USB Key Version of Isadora 3 or 4, see this article for instructions on how to register your USB Key License.

If your computer cannot connect to the internet, see this article for instructions on how to activate Isadora offline.
