When I double click on the install linux mint icon on the desktop, it won't run. Instead, it tells me, "the program is using root permissions without requiring a password." It goes on to say that, "This is not a bug, or necessarily a problem. It's just a warning." The problem is that after I click close on the "warning" box, nothing happens. I tried right clicking the icon, and choosing "run as administrator", but that requires an administrator password.(more on that in a moment.) Then I went to properties for that icon, and copied and pasted the terminal command that the icon invokes into a terminal window, but that also requires a password.
I have asked for the default password on the "newbies" forum, and hopefully that will fix the problem. I still want to know why in the world this doesn't work.
Thanks in advance.

I am frequently right and never in doubt.
