I am having the same problem as this question.
I installed Pervasive v11 (which does have 64bit ODBC drivers) and I still do not see Pervasive listed as a provider when trying to create a linked server in SQL Server Express 2008 R2. Does anyone have any ideas what to try?

You will need to set up a System DSN in order to connect to it using the ODBC drivers from SSMS/SQL Server - simple installing the drivers is not enough. I had to do the same in order to connect to an older instance that our company uses. Here is an excellent link that will help guide you through the process:

Once you have set up the DSN within the System Data Sources you will be able to create a linked server to it.
