[Python.NET] Where does the clr in IronPython look the dll

Hello Everybody I am trying to import dll with clr.AddReference("TCdll") I am getting the following error. Traceback (most recent call last): File "<pyshell#26>", line 1, in <module> clr.AddReference("TCdll") FileNotFoundException: Unable to find assembly 'TCdll'. at Python.Runtime.CLRModule.AddReference(String name) I have loaded the dll in system32 folder. Have I loaded the dll at the right place or do I need to place it anywhere else? Waiting for your replies. Regards Navneet
