I already tried -as I wrote- to run the software as administrator, and to disable antivirus or antispyware but unsuccesfully.
Then, by chance, I discovered why I had that problem: I wanted to install to a different path (not c:/program files but c:/programmi -the italian word for programs-) and I received that error.
Installing to the default path c:/program files everything went ok!
But the best has yet to come: on my hd there's no c:/program files but just c:/programmi!
