    Horizon View Composer Installation Failed (1603)

    arnoldveenema Novice



      We are struggling with an upgrade of Horizon View Composer with any version higher than 7.0.3.

      E.g. the upgrade or fresh install of VMware Horizon Composer 7.3.2-71161120 fails on Windows 2016.

      Error logs shows:


      VIEINSTUTIL: InstallDriver: params = vstor2-ufa, Vstor2 UFA Virtual Storage Driver, C:\Program Files (x86)\Common Files\VMware\VMware Universal File Access\vstor2-ufa.sys, 2, 1, (no load order), 1

      VIEINSTUTIL: Opened Service Control Manager

      VIEINSTUTIL: Created service vstor2-ufa for C:\Program Files (x86)\Common Files\VMware\VMware Universal File Access\vstor2-ufa.sys

      VIEINSTUTIL: Failed to start service (0x241)

      VIEINSTUTIL: Finish install

      CustomAction InstallVstor2Driver.5ACA97E0_7C64_4970_A763_840E81DAAF0B returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)

      Action ended 14:13:17: InstallFinalize. Return value 3.


      After a bit of digging I found that Windows will not start the service because it does not trust the driver vstor2-ufa.sys

      Eventlog shows

      Any idea how to solve this? Is it possible to correct this or manually add a trusted source of something?


      Kind regards,
