In some scenarios, the game will attempt to be launched with 64 bit launch options (notably -Xmx2G), while the 32 bit jvm is being used. This is problematic, as the 32 bit JVM cannot allocate more than ~1GB of memory. See attached for the launcher log.

Please note that this is an edge-case that is not likely to occur in most scenarios. The user in question experienced this on a Surface X tablet, which does not meet minimum requirements for the game in any case. It did however run in 64 bit mode, but launch the game in 32 bit mode (for whatever reason).
