To use Update Manager, you must install the Update Manager Client plug-in, which is delivered as a plug-in for the vSphere Client.

You can install the Update Manager Client plug-in on both 32-bit and 64-bit operating systems.


  • Install the Update Manager server.
  • Install Microsoft.NET Framework 3.5 SP1. You can download it from the vSphere installer.


  1. Connect the vSphere Client to a vCenter Server system with which Update Manager is registered.
  2. Select Plug-ins > Manage Plug-ins.
  3. In the Plug-in Manager window, click Download and install for the VMware vSphere Update Manager extension.
  4. Select a language for the installer and click OK.
  5. Review the Welcome page and click Next.
  6. Read the patent agreement and click Next.
  7. Accept the terms in the license agreement and click Next.
  8. Click Install.
  9. Complete the Update Manager Client installation, and click Finish.
    The status for the Update Manager extension is displayed as Enabled.
  10. Click Ignore if a security warning appears.

    The security warning appears when the vSphere client detects a certificate that is not added in the Trusted Root Certification Authorities store. This is usually the case with the self-signed certificate used by ESX/ESXi hosts by default. For highly secure environments, you must set up a trusted third-party certificate later.

  11. Click Close to close the Plug-in Manager window.


The icon for the Update Manager plug-in is displayed on the vSphere Client Home page under Solutions and Applications.
