Purging RT and Scatter Plugins from Scene?

[3ddesign]

I've been given a file where Vray RT and Vray Scatter were used. I have neither so I'm always getting the annoying missing dll error. Is there a way to purge these plugins from the file?

Dunno for Scatter. For RT it might be worth checking the general tab in the render settings and see if RT is still set as active shade renderer. Other than that there arent any RT specific things if i am not mistaken.
