The vCenter Server system must have a 64-bit DSN. This requirement applies to all supported databases.


Select Control Panel > Administrative Tools > Data Sources (ODBC).


Use the application to create a system DSN.

If you have a Microsoft SQL database, create the system DSN for the SQL Native Client driver.


Test the connectivity.

The system now has a DSN that is compatible with vCenter Server. When the vCenter Server installer prompts you for a DSN, select the 64-bit DSN.
