Uninstall the 2005 management tools? See here: – Jon Seigel Aug 1 '12 at 17:13
I am getting the same error. It's not the installation media, I have tried another ISO downloaded separately. I have 2008R2 installed. Suspect this is a bug. If there are bugs trying to install the basic client tools.. do you really trust features like AlwaysOn and even the engine? – user10613 Aug 3 '12 at 1:46

I got it to install by first uninstalling "Microsoft SQL Server 2012 Native Client" from "Control Panel > Uninstall a program". For some reason, that component had been installed months earlier, and the upgrade advisor never caught it as a problem. Still, the odd installation date caught my eye, and since someone else mentioned the installation began failing with that component, uninstalling allowed me to re-run SQL Server 2012 upgrade successfully after 3 or 4 previously failed attempts pretty much exactly as you described.

This just worked successfully for me after troubleshooting several attempts to upgrade SQL 2008 R2 to SQL 2012. – Mitch Jun 2 '15 at 15:33
