title: SQL Server 2017 Installation Fails on Windows 10
body: <p>I am attempting to install SQL Server 2017 Developer Edition on Windows 10 but I am getting an error "Exception has been throw by the target of the invocation."  That is less than helpful.  </p>

  <p>If I run the System Configuration Checker, the setup administrator rule fails.  I am at a loss to explain the failure since this I have one account on my computer and I am in the Administrator group.  This computer is not part of a Windows domain.  I tried running setup as an administrator by right-clicking run as administrator and got the same results.</p>
  
  <p>Unsure if this is causing the setup failure but I figured it is where I should start.  It is not even starting the setup so I don't think a log file is created that I can look at.  I tried running the setup as administrator and I get the same results.  Ideas on how I can troubleshoot this?</p>

  <p><strong>UPDATE</strong> </p>
  
  <p>Found out the setup log file is located in the folder C:\Program Files\Microsoft SQL Server\140\Setup Bootstrap\Log.  So I checked the error log and the error message was</p>
  
  <p>Unable to load DLL 'sqlmu.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)</p>
  
  <p>Sure enough that file was missing.  So I re-downloaded the ISO and extracted it and now setup runs fine.  Must have been a corrupted download.  Hope that helps somebody.</p>
