I have some problems with uninstalling, please help me

[Uzarra]

I`d like to uninstall qt.. I went to qt enterprise maintenance tool->remove all components->uninstall..
"ENTER YOUR PASSWORD TO AUTHORIZE FOR A SUDO"
Program asked me to enter my sudo password(if I understood it clearly) and I did..
ERROR WHILE ELEVATING ACCESS RIGHTS
And then error.. But I entered it right

Have you got any other ideas how to uninstall program? or please find mistakes in my way..

Run the uninstaller with sudo. Or just remove the data by hand.
