Why is External Mode Real Time Windows Target not supported for 64-bit machines and why does Simulink Coder 8.2PR (R2012a) crash when I use the External Mode Real Time Windows Target?

When I use the External Mode of the Real Time Windows Target it crashes.

[MathWorks Support Team]

This bug has been fixed in Release 2012b (R2012b). For previous product releases, read below for any possible workarounds:

External Mode with a 64-bit Windows platform is supported beginning with Real-Time Windows Target 4.1 (R2012b).

The fact that External Mode was not supported on 64-bit Windows was a

temporary limitation. The fact that an attempt to use External Mode from 64-bit Windows can lead to a crash is a Prerelease bug and the development team was working towards fixing it in as early R2012a general release, so that there is a proper error message instead of a MATLAB crash.
