    Hi there, 

    Thank you for reaching out, We would like to further investigate this issue so I would like to ask for your assistance in creating a case and then re-create the error that you're getting while Running Process Monitoring and collecting SDU then attached the logs on the case that you're going to create.

    Once done, you can try running the installation package via CMD and add this syntax `--nocompetitorremoval' then observed the installation process. Capture any errors you encounter via snapshot and share it with us. Make sure you open your CMD via Elevated access before performing the said action.

    Hello,

    I'll create a case.

    Besides, with the syntax I had another error (elevated CMD):

    The error 4551 = 

    ERROR_SYSTEM_INTEGRITY_POLICY_VIOLATION

    Your organization used Device Guard to block this app. Contact your support person for more info.

    Does that help?

    It's help yes and no, yes because I had something to search, and no because I'm on Administrator Account.

    Thank you for your help

    I suspect you have a policy that prevents executables from running from user's temp locations.

    Software Restriction Policies in GP?

    If so and you can't change that, you could try copying the CID from the distribution point to the server E.g C:\S000\

    Launch a cmd prompt as system using psexec, e.g.

    psexec -i -s cmd

    PsExec - Windows Sysinternals | Microsoft Docs

    From that new cmd prompt running as system (check with whoami), you can CD to C:\S00  etc and run setup.exe

    Software restriction policies don't apply to System user.
