Nokia Ovi Suite 2.2.1.23 Installation operation failed

Hi!
Recently I have downloaded Nokia OVI Suite 2.2.1.23 from Nokia website. But whenever, I am trying to install the latest version of Nokia OVI Suite 2.2.1.23, I am just getting a message appearing on the PC saying: "Installation operation failed. Unknown error code: 1612". I have tried to stop it in so many ways but failed.
I have used: Nokia PC Suite Cleaner, Uninstall OVI Suite, PC Connectivity solution and Nokia Connectivity cable drivers from Add/remove program Delete the files from.
