Are you running Vista, Teracia ? If so, running something as an adminstrator isn't the same as running it from an administrator account(!).

Right click the Keyclone installer (keyclone_current.eexe) and select "Run as administrator". Do this even if you're currently logged in as an administror, and all your problems will go away.

One of the many irritations of Vista that we'll all get used to eventually, I'm afraid....
