    Maybe not enough rights, try out from under the admin. It would be good to see the text of the exception. - αλεχολυτ
  • admin doesn't help - codename0082016
  • Well, what about the 'Message' exceptions? - αλεχολυτ
  • The machine is not in the domain? Home PC? - isnullxbh

Open MSDN, look for the RegistryKey.CreateSubKey function, scroll to the Exceptions section, find our IOException , and read the condition under which it occurs:

The nesting level exceeds 510.

-or-

There is a system error occurred, such as deletion of the key.

Humble, so creating your subkey in HKLM is not allowed.
