Installing a vCenter Server update on Windows Server 2008 or later with User Account Control (UAC) turned on requires the logged in user to have Administrator-level privileges. You can elevate the privileges of Administrators group members to the Administrator level.
Alternatively, you can turn off UAC in the User Accounts control panel, and turn it back on after the update is complete. The computer must be restarted each time you change this policy setting.
- In the Administrative Tools control panel, double-click Local Security Policy.
- Under Local Policies, select Security Options.
- Double-click User Account Control: Run all administrators in Admin Approval Mode.
- Select Disabled and click OK.
- Restart the computer.
All members of the Administrators group can install the update.
