body: <p>Installing Microsoft® ODBC Driver 17 on windows 10.

  rebooted but not fixed.<br>
  4 reboots and then tried install again.  Same issue.</p>
  
  <p>Microsoft ODBC 13 driver installs and uninstalls without any issues.</p>
  
  <p>I've reviewed Microsoft support site and found nothing that describes this issue.<br>
    There are notes about odbc 13 and 17 causing conflict.  odbc 13 is not installed.</p>
  
  <p><a href="https://support.microsoft.com/en-us/help/2008982/you-are-repeatedly-prompted-to-restart-the-computer-when-installing-sq" rel="noreferrer">checked this potential</a> for SQL Server install requiring reboots, but nothing in my registry for PendingFileRenameOperations.</p>
  
  <p>Has anyone found the clue that Driver 17 is using to think it needs another reboot to continue?  I need to get SSMS installed and it has a dependency on ODBC Driver 17.</p>
  
  <p>windows 10 updated to current.
