how to open two accounts in the eternal game

Well I've tried, and I could not open the second game of eternal Dekaron while someone has a file which opens two games? I await answers
:bandit:

u will have to put a copy of it on an external to open a second window if the exe wont let u open it then this will do the trick

or setup user accounts w/o passwords because thats annoying an run multiple copies that way.
