From your wording and the examples given it isn't clear to me where
"myClass" resides. However, assuming myClass is published through an
ActiveX component...

The CreateObject function takes as its argument an AppID or ProgID
which must be registered in the Registry.

Look under 
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\AppID\{AppID_value}
to see if it is registered.
