Question; does the key Fowles already exist at the point your performing AddKey? If not, try this and see what happens:

code:

---

$key = "HKEY_LOCAL_MACHINE\Software\Fowles"
$ReturnCode = ExistKey ("$key\customdic")
If $ReturnCode=0
  goto EndCommon
else
  call "wordic.kix"
  $ReturnCode = AddKey( "$key" )
  $ReturnCode = AddKey( "$Key\customdic" )
Endif
