Hi Ashkir,
Things should be fast. So your saying it never finished detecting games?
If I can take a peek at your "minion0.log" and "minion.xml" that would allow me to see what is going on. They are located in a folder called .minion under your user folder.
Windows:
C:\Users\<your windows username>\.minion\
OSX:
~\.minion\
Do you have a lot of hard drives, slow usb drives or network drives mounted on your system? If so we have an update coming out soon that will prompt you to choose what drives Minion should search for games. Currently Minion scans 4 folders deep on any drive it has access to to find the Wow.exe
Thanks for helping us test Minion! We need to find these bugs
