title: fatal error during installation (0x80070643) SQL Server MAnagement Studio: A valid destination folder for the install could not be determined
body: <p>I am installing the Microsoft SQL Server Management Studio (17.2).</p>
  
  <p>It was installed before, but I re-install it because I forgot the admin password (shouldn't do this actually).</p>
  
  <p>However, the re-installation is not successful. The same error message occurs:</p>
  
  <blockquote>
    <p>fatal error during installation (0x80070643)
    SQL Server MAnagement Studio: A valid destination folder for the install could not be determined</p>
  </blockquote>
  
  <p>I've found one solution here</p>
  
  <p><a href="https://stackoverflow.com/questions/38373324/a-valid-destination-folder-for-the-install-could-not-be-determined-when-installi#">A valid destination folder for the install could not be determined when installing SQL Server Management Studio 2016</a></p>
  
  <p>But it didn't work on my machine. I even couldn't find the BootstrapDir.</p>
  
  <p>Any ideas what I might look for to solve this problem?</p>
  
  <p>Thanks.</p>
