Hi Mary & Margie.
This is correct, the file that you have downloaded is the resource pack for ActivInspire. You will need to click on the red icon which only says "Download" inside the red box.
Once ActivInspire is installed, you can insert the resource pack by going into File>Import>Resource Pack to my shared resources/to my resources.
I hope this information helps.
