vCenter Server Software Requirements
Make sure that your operating system supports vCenter Server. vCenter Server requires a 64-bit operating
system, and the 64-bit system DSN is required for vCenter Server to connect to its database.
For a list of supported operating systems, see the VMware Compatibility Guide at
http://www.vmware.com/resources/compatibility.
vCenter Server requires the Microsoft .NET 3.5 SP1 Framework. If it is not installed on your system, the vCenter
Server installer installs it. The .NET 3.5 SP1 installation might require Internet connectivity to download more
files.
NOTE If your vCenter Server host machine uses a non-English operating system, install both the Microsoft .NET
Framework 3.5 SP1 and Microsoft .NET Framework 3.5 Language Pack through Windows Update. Windows
Update automatically selects the correct localized version for your operating system. The .NET Framework
installed through the vCenter Server installer includes only the English version.
If you plan to use the Microsoft SQL Server 2008 R2 Express database that is bundled with vCenter Server,
Microsoft Windows Installer version 4.5 (MSI 4.5) is required on your system. You can download MSI 4.5 from
the Microsoft Web site. You can also install MSI 4.5 directly from the vCenter Server autorun.exe installer.
The VMware vCenter Server Appliance can be deployed only on hosts that are running ESX version 4.x or
ESXi version 4.x or later.
