1. Make sure the Dynamic Link Library (DLL) is registered.
   Regsvr32.exe method:
   1. Open Windows Explorer and use the Find tool to search for regsvr32.exe.

   Right-click register method:
   1. Open Windows Explorer and navigate to arcgis > arcexe81 > ArcObjects Developer Kit > Utilities.
   2. Double-click register_in_menu.reg. This adds registration tools to the right-click menu.

      • If the DLL has a pathname greater than 128 characters, it may not have registered correctly.
