You make it sound like getting a 64-bit system is easy. Migrating from 32-bit to 64-bit in the same machine involves a clean install of Windows 64-bit. =3=
Also the minimum spec (without bit-architecture mentioned though) should be the basis of if the game at least works on one 's machine or not. ...though I guess that doesn't matter for the issue at hand atm.
Odd how this isn't an issue on other-region Soulworkers though...or maybe it was not/was less reported, or at least I didn't hear anyone from SW JP reporting it around.
