I have looked back at these threads and found one I posted earlier. I have downloaded the first link and installedut it came with an error message. I ran the commands it gave and everything seems ok.
When I try to get the second link (and the third) I get a 404 not found error.
Can you help again ?
EDIT When I go back to the desktop the' Package Installer ' error message is still there and I can't delete it ?
