>variable "hkey_local_machine" no found is the error message

It requires that you have the FFC Registry class available as well as the Registry.H include file.

I am also having some problems with it (I've never attempted it until now ;-)) so another suggestion would be to use DSNless Connections in your DBC. Choose the Connection string option when creating the connection and input the necessary information to connect to the remote data. See Message#476027 for an example of the data you need to add to the Connection String field.

HTH.
