When I am running the .NET demo application, I receive the following error: Retrieving the COM class factory for component with CLSID {B0200A80-3C4B-4A42-ACC1-F9B11939ED5D} failed due to the following error: 80040154.

This error means the component is not correctly registered on this PC, or you are trying to run the application in 64 bit mode, while only the 32 bit control has been registered.

To register the 64 bit control, run the following from the command prompt:

REGSVR32 <path to gpsctl64.dll>

Or to register the 32 bit version of the DLL:

REGSVR32 <path to gpsctl32.dll>

By default, the DLL files can be find in the "Program" folder of the installation.

NOTE: When using Windows Vista, 7 or 2008, make sure you run the command prompt as an Administrator, or make sure UAC is turned off.
