Create a linked server 2008 SQL Express to Pervasive

I installed 64bit version of SQL Express and I initially installed Pervasive 10.0. Did not see Pervasive show up a provider, in MS Visual Studio, when trying to create a linked server. I downloaded a copy of Pervasive 11 which has 64bit ODBC drivers, thinking that was the problem. I installed v11 and still do not see Pervasive listed as a Provider. Any ideas on what I am doing wrong? Thanks for any help.
