I was installing mirc on a windows machine 10 machine for the first time and when I tried to enter my registration key was asked what program I wanted to use to open mirc (I had installed and opened the program by this point, was at the title screen where I clicked register) I picked chrome because none of the offered choices made any sense and was taken to the download page of the website and despite closing mirc, uninstalling mirc even using using iobit to get rid of every last trace of mirc before doing a reinstall the same thing keeps happening! How do I fix this and what program should I use to open mirc?
