interop with Windows WMI using the COM package at --

I try compile WMIDemo.hs but recive error:
[code]
c:\htest>ghc --make WMIDemo.hs
[2 of 2] Compiling WMIDemo ( WMIDemo.hs, WMIDemo.o )
WMIDemo.hs:24:2:

Hi,
please upgrade to the latest version - 1.2.2 - of the com package for
this example,
http://hackage.haskell.org/cgi-bin/hackage-scripts/package/com
There's been some improvements to the lib, esp. the handling of enumerations
(which is where that type error is coming from.)
