M2 - Right-click menu isn’t working

Problems
a. When right-clicking an element in the containment tree as shown below, the Syndeia menu item shown highlighted at bottom left is missing.
b. When right-clicking an element in the containment tree as shown below, the Syndeia menu items shown at bottom right (Dashboard, Open Connected Artifacts, etc.) are not responding when clicked.

Solutions

a. If Syndeia menu is missing entirely, try one or more of the following:

Check that the Syndeia installation folder looks correct according to step 7 of the installation instructions in the User Guide
Check that Java is set up correctly according to the User Guide Java setup instructions
Check for license validation messages in troubleshooting item M3 - License validation fails

b. If Syndeia menu items are shown but not responding when clicked, check for license validation and/or checkout messages as shown below. If you do not see the notification window, press Ctrl+M

If you see a message that license validation failed as shown above, make sure a valid license is placed in correct location according to step 8 of the installation instructions in the User Guide.
If the messages state that a license is not checked out, check out a license.
