The vCenter Server system must have a 64-bit DSN. This requirement applies to all supported databases. By default, any DSN created on a 64-bit system is 64 bit.

1

Install the 64-bit database ODBC drivers on your Microsoft Windows system.

The default installation location is C:\Program Files\VMware\Infrastructure\VirtualCenter Server.

2

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

3

Use the application to create a system DSN and 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.
