An update:
Toad have changed a little. If you are using a client, you can optionally ADD / MODIFY* a license to the current version (you dont need to install the latest version - only update the license). *This option will appear in the splash screen, when you run Toad.
To do so, navigate to Toad website, and ask to download the latest version trial.
You’ll be able to download, but it’s not needed (if the version you’re currently using is fine).
Simple read the e-mail you will receive (when you download latest trial version), and add license info.
License Number: (read your e-mail)
Toad for Oracle Trial License Key: (read your e-mail)
