I was not prompted to install a plugin when launching a session from my browser and do not have the options under my listed remote computers to transfer files, print or listen to the sound. Is it possible to download the plugin and install in manually?

Ive seen that before and when I went to click and install the plugin nothing happened. I never did find out what was the actual plugin that needed to be installed.

This was on CID but now I use Firefox and I never got that warning to install a plugin.
