For "Key not valid for use in specified state" errors try moving the folder RSA from C:\Users\<User>\AppData\Roaming\Microsoft\Crypto\RSA to say C:\RSA (just in case there should be a need to restore it) then try installing again. This folder appears to act as a cache and should be rebuilt automatically as required.

For further problems installing iTunes see Troubleshooting issues with iTunes for Windows updates.
