You have a whole folder of .aaxplugin files they are your plugins.

Look at C:\Program Files\Common Files\Avid\Audio\Plug-Ins

If you are not seeing the plugin load, it's likely not in that folder and you likely have not actually installed it.

There should be an installer. You downloaded something from your Avid account... you mean from the Avid account website? Then you need to manually run the installer (as an Administrator), or if you mean via Avid Application Manager then it should start running the installer for you. Make sure if the installer is trying to run it's not hidden behind other Windows on your desktop and your account has Windows Admin privileges.
