Plugin errors shown on Mac

Greetings,
I have a Macbook Air that runs on Lion 10.7.2 and I wanted to download a plugin called NP_2020Player_IKEA.plugin from https://kitchenplanner.ikea.com/au/UI/Pages/VPUI.htm.
The error that comes up when I try to mount the plug in is shown below.

Error message:
NP_2020Player_IKEA.plugin
