Try placing symbol from ...\tools\capture\library\pspice\advanls\CONTROLLER.OLB. It may be using the symbol from tools\capture\library\regulator.olb or tools\capture\library\Misc2.olb. These libraries do not have simulation model associated with them and you will get above error.
In case you are using the symbols from ...\tools\capture\library\pspice\advanls\CONTROLLER.OLB, please check the PSpice setup. You should have nom.lib configured as GLOBAL lib and you should have ..\tools\PSpice\Library folder in Library path, under Simulation Setting, Configuration File, Library TAB.
Hope this helps.
