The Hatt

Not sure if I have misread something on this page: https://pscan.uk/install/linux.html

I have the pscanloader file in a folder. But when I double click the icon, I get a message saying 'There is no application for executable...'

I don't know what this means.

This is a fresh install of Ubuntu, I've done nothing but run the Ubuntu installation and then download the pscanloader file.

Thanks.
