Hi,

here are the logs from the log collector: vslogs.zip

However I also have additional information: I clicked on 'abort' / 'abbrechen', but the installation did not rollback or abort.
As I had some work todo in VS2015 and it refused to start while the VS 2017 RC installation was running, I rebooted.

After reboot, the installation came up again, this time trying to install an Android Emulator. Also this got stuck and could not be aborted. Again, after another reboot, the installation of the CorodvaTools6.3.1 got stuck at 51%.

After a few hours I could not see any other means than to kill the installation process via Taskmanager to be able to open VS 2015 and do my work.

Thanks for your investigation.
