SQL Server Express 2014 Installation directory I face recently a problem when starting SQL Server Management Studio. As it can't start, I uninstall it. When trying to install it again, I am asked to select the installation folder of SQL Server. 



Unfortunately, nor the MSSQL folder, nor its Binn child solved my problem. Can somebody help get the right folder ?

Edit : 
I've succeeded installing SSMS again, but I still can not run it. It is showing this message : 
 

Finally, I cannot guess the source of the problem.
That dialog asks you for the installation media, pay attention. You need to specify the location from where you've run the original install. That is not an Express uninstall, you are uninstalling a licensed SSMS, so you should provide your original, licensed, CDs.
