VBScript and SMO

I've have a vbscript that utilizes sql-dmo and accesses sql 2005 and sql2008 r2(with back ward compatability).  I now have a sql 2012 server where this script no longer works.  I've attempted to change the sql-dmo to smo per the documentation, but am getting an error right from the start. 

Set objSqlServer = CreateObject("Microsoft.SQLServer.Management.SMO.Server")  returns "Microsoft VBScript runtime error: ActiveX component can't create object: 'Microsoft.SQLServer.Management.SMO.Server'"

Does this not work using vbscript?  If not, what is my best course of action.

thanks in advance for any help on this.
