To determine the version of your plugin, open the plugin window and click on the Slate logo in the top left corner. This will show you the version number of your plugin. Trigger 2 is the only plugin that does not operate this way and you will need to go the settings tab of the Trigger 2 plugin window. At the top it will say Platinum or EX followed by the version number. If you are unable to even open any of the plugin windows, then please refer to the plugin paths section of the knowledge base. You can go to each path, pending your operating system, and check the version number there. If you need further assistance, then please submit a request to speak with a support agent.
