There are several reasons why the Update Manager installation fails during installation.
For a successful Update Manager installation, ensure that:
  • You use an administrator account on the vCenter Server.
  • The username and password exist on the vCenter Server.
  • The password for the account is alpha-numeric and does not contain any non-english characters.
  • A vCenter administrator role is assigned to the Update Manager administrator group and the login roles.
  • You use the initial account that was used when installing the vCenter Server, when Update Manager prompts for the username and password.

    : If ActiveDirectory user credentials are used, the password complexity requirement has special characters mentioned, but they are not mandatory.

  • There are no anti-virus or firewall programs blocking the installation.
If the installation continues to fail, you must uninstall Update Manager, clean up the installation directory and registry entries, and reinstall Update Manager.
To uninstall and reinstall Update Manager:
  1. Uninstall Update Manager from Add/Remove Programs.
  2. Open Task Manager and verify if any Update Manager processes are running. Ensure that the rdevServer.exe process is stopped before proceeding.
  3. Delete or move the log files from %temp% and \Windows\Temp folders.
  4. Delete the Windows service vmware-ufad-vci manually and reboot the machine. Microsoft's utility Instsrv.exe can accomplish this. For more information on Instsrv.exe, see the Microsoft knowledge base article 137890.
  5. Clean up Update Manager installation directory and remove the Update Manager folder from the root install directory.

    • The default location is %ProgramFiles%\VMware\Infrastructure\Update Manager.
    • Ensure to back up the registry before making any changes.

  6. Clean up registry entries under HKLM\Software\VMware, Inc.\VMware Update Manager.
  7. Run the installer again to install VMware Update Manager.

    Note: After the reinstall it may be necessary to re-create the 32-bit ODBC connection for Update Manager. For further details, see Creating a 32bit DSN on a 64bit Windows machine (1010401).
