How can I configure all Windows Installer installations to run with elevated privileges?

To run all Windows Installer installations with elevated privileges, perform the following steps:

  2. Expand Computer Configuration, Administrative Templates, Windows Components, Windows Installer.
  3. Double-click “Always install with elevated privileges.”
  4. Set to Enabled, then click OK.
  5. Expand User Configuration, Administrative Templates, Windows Components, Windows Installer.
  6. Double-click “Always install with elevated privileges.”
  7. Set to Enabled, then click OK (you must enable this GPO under both the User Configuration and Computer Configuration sections for it to take effect). Click here to view image

  2. Navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer registry subkey.
  3. From the Edit menu, select New, DWORD Value.

  7. From the Edit menu, select New, DWORD Value.
