    Hi @Irfan Mughal ,

    Run SharePoint setup file as administrator then compare the result.

    If the issue still exists, please check these following methods that might help:

    Method 1 :

    1. Click Start on the Windows taskbar, and then click Run.
    2. On the Run window, type gpedit.msc, and then click OK.
    3. On the Group Policy window, navigate to Local Computer Policy, then Computer Configuration, then Administrative Templates, then Windows Components, and then Windows Installer.
    4. Double-click Prohibit non-administrators from applying vendor signed updates.
    5. If configured, click Disabled, and then click OK.(In my environment, it is not configured.)


    Method 2:

    1. Start > run regedit
    2. Browse the registry to HKLM\Software\Policies\Microsoft\Windows\Installer
    3. Create: DisableMSI Type: REG_DWORD value = 0 (0 should allow you to install, it was originally 1) [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Installer]

    We have encountered the exactly same issue with SharePoint 2016. Starting the SharePoint 2016 setup gave this error. Below solution worked for me.

    Instead of mounting the ISO and running the setup wizard, extract the ISO separately on drive and then run the installation.

    You can check complete details here.
