If your plan is Business Plan (or higher), you can use Exploratory in Offline Mode by setting up an Offline License Key.
If your plan is currently not the Business Plan, please access the Update Plan Page and select the Business Plan or higher.
Click the gear icon next to the project name.
Click the Offline License tab on the Exploratory System Configuration Dialog.
If you don't have an Offline License Key yet, you can generate it by clicking "Generate License Key" button in the above Dialog.
It will open up a browser like below so copy the Offline License Key shown on the page.
Then go back to Exploratory Desktop and paste it and click the Save button.
If you already have an Offline License Key, paste your Offline License Key into the License Key input field and click the Save button.
