Happy new Year

Back to work and out IT being busy during the break managed to uninstall AutoCAD I have set for Equipment module. Trying to re-set profiles, but AutoCAD is ignorant to this ... no CadWork Equipment commands run. I am able to load menu, but not Application. Manual APPLOAD of CADWorxEquipment.arx comes with following message: Cannot find a dll or other file that it needs. Any ideas ? Thanks in advance.
