There was a conflict between Framework 4 and PDN... I delete the framework and the installation run ok!!
Thanks to all for the replies... problem solved!!

I was a .10 version proud user...now I cannot reinstall the .10 version... the error is the same!!!!!!!
I'm blocked... I don't know what to do...<family-friendly forum>!!
If I think that 5 days ago .10 release was perfect....
