[ubuntu-uk] run application in a terminal

[Norman Silverstone]

I have searched and failed to find an answer to my problem, perhaps I am
not asking the right question. On my desktop there is a folder
containing some software called VueScan. To run the software I open the
folder, find a blue square standing on a point and double click and away
we go. What I would like to try is running the programme as root how do
I do this, please?
