EasyBCD doesn't start

I'm running two OS in dual-boot on this PC (x64) : Windows 10 Pro (1607) and Kubuntu 16.04, which are installed on two different discs. I just wanted to change the boot disc, and therefore EasyBCD would be useful. The problem is : I couldn't launch it (2.3 Beta build 205). I uninstalled it, and when I tried to reinstall it, I got the following notification (attached file).
Any idea of what happened ?
