      Verify the Windows Installer

      The Windows installer service adds, modifies, and removes any applications that are provided as a .msi package. If this service is disabled any services that depend on it will fail to start.

      1. Click the Windows key + R, type Services.msc into the field and click Enter.
      2. Locate the Windows installer service in the services window, right-click it and select Properties.
      3. Select Automatic from the Startup type drop-down and click Start.
      4. Click OK and try the installation again. If the same message appears, the Windows Installer service could be corrupted.
      5. Download and install the last version of Windows Installer: http://www.microsoft.com.
      6. Try the installation again.
