It worked, but do you think it will be possible soon to run miRC without using the compatibility mode?

Well its not a 64bit app now is it, so it likely would have to use compatibility mode, and I doubt a second version well come out tell most people are on 64bit, then it well be a change over like the mirc16/32 changed over to mirc just in 32bit etc etc. I wouldnt like to support 2 platforms when most users are on one of them.
