So, an installation of mine failed (SQL Server Data Tools 2015) and then, there was a restart that was triggered and my installation was cancelled out before I was able to finish it. when I try running the installation it asks me to repair or uninstall.
I am just curious how exactly repair works behind the scenes. Will it verify that things are missing and install the things that haven't been installed at this point?
Or should I uninstall and reinstall.
