title: SSMS 18.4 installation will not run
body: <p>I am having trouble installing SSMS on a fresh installation of Windows 10 - on a new Dell XPS 15.</p>
  
  <p>I am installing the latest version (18.4) from here: <a href="https://docs.microsoft.com/en-gb/sql/ssms/download-sql-server-management-studio-ssms" rel="nofollow noreferrer">https://docs.microsoft.com/en-gb/sql/ssms/download-sql-server-management-studio-ssms</a></p>
  
  <p>When I run <code>SSMS-Setup-ENU.exe</code> I get the <code>User Access Control</code> dialogue, I say <code>Yes</code> and nothing happens.</p>
  
  <ul>
  <li>I cannot see any processes starting in Task Manager.</li>
  <li>Logs indicate that the installationg cannot start. From googling this error suggests that I'm missing a version of dotnet framework. </li>
  </ul>
  
  <p>I have installed Visual Studio 2019 + all the dotnet frameworks (everything from 4.6 to 4.8) + Dotnet Core.</p>
  
  <p>Does anybody have any ideas - what am I missing or doing wrong? :/</p>
  
  <p>Thanks for your help!</p>
  
  <p>Error (ommitting all of the noise)</p>
