小弟在使用Matlab2007a的Link for Tasking工具时，在Start菜单中配置正确配置了C166配置后，选择“Launch and test communication with Tasking EDE"时，出现如下错误：
Setting Template Application Project: $(MATLAB_ROOT)\toolbox\rtw\targets\tasking\tasking\default_project_options\c166\ede\app_c166_sim.pjt
Setting Template Library Project: $(MATLAB_ROOT)\toolbox\rtw\targets\tasking\tasking\default_project_options\c166\ede\lib_c166_sim.pjt

Updated "C166" configuration in TASKING Target Preferences.

??? Error using ==> tasking.edeapi.validateToolchainDirectory at 36
Could not read the toolchain version from the currently open EDE!

EDE工具已经启动，Link for Tasking不能连接和正常运行，EDE工具版本是：TASKING program builder v7.5 r2
请教大家，看是什么问题？
