FXCOP lance une exception sur la ligne de commande, mais pas dans l'interface graphique?

Question

J'ai un projet FXCOP 10.0 qui s'exécute bien via l'interface graphique FXCOP, mais lorsque je l'exécute dans l'application FXCOPCMD de commande (que je souhaite utiliser dans le cadre de notre processus de construction automatisé), il génère l'exception suivante - apparemment en essayant de charger assemblages.

Je ne trouve rien de révélant sur Google, alors quelqu'un a-t-il des idées ce qui pourrait provoquer cela?
