I don't speak your language so I can only assume you are having trouble installing your McAfee software. If you could post in English that would help me and others to help you.
Please try to run the MCPR removal tool found at the top of this page under Useful Links. MCPR will remove any McAfee files in your computer that might be in there from your attempted installation of the software.
If you are having trouble installing follow the recommendations in this link and be sure to use the McAfee preinstall tool which is included in the link http://service.mcafee.com/faqdocument.aspx?id=TS100119
Si prega di mettersi in contatto con i nostri tecnici chat qui e che vi aiuterà a risolvere il problema.
