Troubleshoot an add-in

I've finished re-packaging my macro as an add-in (currently as an ocx library) and attempted to register it with SolidWorks through the following registry additions:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Solidworks\AddInsStartup\{FFFFFFFF-EEEE-DDDD-CCCC-BBBBAAAA0001}]
@=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\SolidWorks\AddIns\{FFFFFFFF-EEEE-DDDD-CCCC-BBBBAAAA0001}]
@=dword:00000000
"Title"="Test: Reg-Title of OCX"

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{FFFFFFFF-EEEE-DDDD-CCCC-BBBBAAAA0001}]

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{FFFFFFFF-EEEE-DDDD-CCCC-BBBBAAAA0001}\InprocServer32]

@="C:\\Program Files\\SolidWorks (2)\\SolidWorks (2)\\Plugins\\AddIn_OCXTest.ocx"

However, I a presented with the error that the add-on “…cannot be loaded. Either the Add-In or one of it’s components is  missing.”

Can anyone assist?

Thanks
