Sorry guys, but this is not the way to do it!
You may find in the future you will have problems; .dll and .exe COM components need to be registered correctly otherwise you may have issues with incorrect Class IDs, Interface IDs and Type libraries in the Windows registry.
These components are meant to be self registering but if you come across a problem like this you MUST use the 'regsvr32' utility to register your COM component, in this case a DLL.
From the command prompt:
regsvr32 [/e] [/m] <dllname1 dllname2>
In this case - regsvr32 <yourdllname> (Without the < and >!)
<your dllname> should be the full path of where your file is located; C
windows\system\CTL3D32.dll
