How to install Distributed Replay (dreplay.exe) for SQL Server 2017
@Randi Vertongen: You really find dreplay.exe in the location you mention just by installing the DReplayClient and the DReplayController from the SQL 2017 ISO? I just installed the Controller and the Client and it is definitely not there. As mentioned in my post in the MSDN Forum  it can be installed by installing SSMS 17.x which I am going to do now - but that cannot be the solution. I have opened a Connect Item back in the days - Maybe you would like to upvote it:
