Topic: fatal error LNK2001?

I'm creating a plugin for acrobat using Visual C++ 6 and Acrobat 5 SDK. I want to create a plugin that will basically expose the digital signature plugins methods to the outside world.

I have done the following:

1/ Created project using ATL COM Wizard. Selected 'Dynamic Link Library (DLL). Left everything else unchecked.

2/ Inserted an ATL object. Insert->ATL obj. In the 'ATL Object Wizard' I selected a 'Simple Object' in the Objects category.

3/ In 'ATL Object Wizard Properties' I inserted a short name. On the 'Attributes' tab I select 'Apartment', 'Dual', and 'Yes' for Aggregation. Left the check boxes blank.

4/ Included SDK headers to project i.e. Project->Settings->C/C++->Project Options and set the paths. Set the category to 'Pre-processor' and added the following paths "C:\Program Files\Adobe\Acrobat 5.0 SDK\PluginSupport\Headers\Headers,C:\Program Files\Adobe\Acrobat 5.0 SDK\PluginSupport\Headers,C:\Program Files\Adobe\Acrobat 5.0 SDK\PluginSupport\Headers\ADMHeaders,C:\Program Files\Adobe\Acrobat 5.0 SDK\PluginSupport\Headers\ADMHeaders,C:\Program Files\Adobe\Acrobat 5.0 SDK\PluginSupport\Headers\ADMHeaders\IADM" to "Additional Include Directories:".

5/ Copied Pimain.cpp and ***Init.cpp from AddDispInterface example (changed name of ***Init.cpp file).

6/ In Project->Settings->C/C++ I changed category to preprocessor and added WIN_ENV to the preprocessor definitions.

When I build the project I am now getting the error message "error LNK2001: unresolved external symbol "void __cdecl RegisterCOMServer(void)" (?RegisterCOMServer@@YAXXZ)". Can anyone tell me why?
Any help would be much appreciated. Thanks.
