installing without deleting old version of MS

like the subject says.. is there a way to install v62 without erasing older ones? so i tried installing v62 on a new folder named nexon2 but it scanned through my computer and deleted the v55 files. this is mainly cuz my brother wants to play v55 but i want to play here.. so for now i deleted v62 and reinstalled v55 but need to install v62 again.
please help. thanks

uhmm.. since the newer version of ms is out and its v62..
so Nexon thought of a good idea of getting rid of the most of the ps server..
so either you choose between GMS or private server..
and yeahh. there is no other way for v62.

idk if there is a way but i do play all 3 (vs55, vs62, gms) i downloaded the folder instead of the setup. if that helped
