John,
Make sure also other DLL like GRINTL32.dll is there (you can use depends from VS tools).
If it's saying INVALID CLASS STRING then class is not known. ie: On my system I get it if I say 'MSGraph.chart.9' but not 'MSGraph.Chart.8' or just 'MSGraph'

You can test it from VFP also :

lparameters tcClass
#DEFINE HKEY_CLASSES_ROOT    -2147483648
#DEFINE ERROR_SUCCESS		0	&& OK

DECLARE Integer RegOpenKey IN Win32API ;
	Integer nHKey, String @cSubKey, Integer @nResult

DECLARE Integer RegCloseKey IN Win32API ;
	Integer nHKey

local lnKey
lnKey = 0
llRetVal = ( RegOpenKey(HKEY_CLASSES_ROOT, tcClass, @lnKey) = ERROR_SUCCESS )
if llRetVal
  RegCloseKey(lnKey)
endif
CLEAR DLLS
return llRetVal
