The FFC contains a class that can read and write from the registry, Registry.VCX, with a class named registry.

#INCLUDE REGISTRY.H
oReg = NEWOBJECT('Registry','Registry.VCX')
IF oReg.GetRegKey('',"<i>ProgIDofControl</i>\CLSID",HKEY_CLASSES_ROOT) # 0
   *  ProgID is not correct, so register
ENDIF
cCLSID = SPACE(0)
=oReg.OpenKey("<i>ProgIDofControl</i>\CLSID",HKEY_CLASSES_ROOT)
=oReg.GetKeyValue('',@cCLSID)
IF oReg.GetRegKey('',cCLSID,HKEY_CLASSES_ROOT) # 0
   *  Missing CLSID
ENDIF

It gets painful. Reregistering the control is generally safe, and may avoid version problems if the ProgID doesn't change between versions.
