You can install or upgrade to vCenter Server on both 32-bit and 64-bit operating systems.

Even though vCenter Server is supported on 64-bit operating systems, the vCenter Server system must have a 32-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 ODBC drivers.

For Microsoft SQL Server and DB2 database servers, install the 64-bit database ODBC drivers on your Microsoft Windows system. When you install the 64-bit drivers, the 32-bit drivers are installed automatically.

For Oracle database servers, install the 32-bit database ODBC drivers on your Microsoft Windows system.

Note

The default install location on 64-bit operating systems is C:\VMware.

2

Run the 32-bit ODBC Administrator application, located at [WindowsDir]\SysWOW64\odbcad32.exe.

3

Use the application to create your DSN.

You now have a DSN that is compatible with vCenter Server. When the vCenter Server installer prompts you for a DSN, select the 32-bit DSN.
