Installing Security Development Tool in AX 2012

i am trying to install Security Development Tool in AX 2012, but it says that the model with same name already exists. I checked the installed models but i cannot find anything with the name matching Security in installed models. I want to uninstall the model & try installing the Security Development tool. Can anyone provide me with the name of Model by which the tool is installed?

Thanks,
