Issue Installing SSMS V17.0 When I try to install SQL Server Management Studio, Version 17.0, I receive the following error message: 


  "The Generally Available (GA) version of SQL Server Management Studio
  (SSMS) v17.0 cannot be installed because a pre-release version of SSMS
  is installed on your computer. Uninstall the pre-release version of
  SSMS from 'Add/Remove Programs' in the Control Panel and run SSMS
  setup again."


I uninstalled the pre-release version, but still have the issue. When I look at the log file, the condition that is causing the problem is 


  [1118:18D4][2017-05-09T16:05:55]i052: Condition 'NOT RCBitsInstalled
  OR (RCBitsInstalled > "2016.140.17030.0" OR RCBitsInstalled &lt;
  "2016.140.0.0")' evaluates to false.


But looking into the log file further, that value seems fine.


  [1118:18D4][2017-05-09T16:05:55]i000: Setting version variable
  'RCBitsInstalled' to value '2016.140.16000.64'


Anyone know a way around this? Thanks!
Delete the folder C:\Program Files (x86)\Microsoft SQL Server\140\Tools\ and then try the installer again. You may need to reboot to release all file handles.
