Hi William, As with the recent message about Demeter on Mac-with-Parallels, I suspect this is an issue with how the PATH is set. It looks to me like you don't have all the path locations set correctly, though it also appears that it is finding the DLL, just not recognizing it as a Win32 DLL That probably means some other DLL is interfering, but I'm not certain of that. I would suggest setting path explicitly to C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\strawberry\perl\bin;C:\strawberry\perl\site\bin;C:\strawberry\c\bin;C:\strawberry\c\bin\gnuplot\bin; You could even try putting this at the top of dathena.bat (and dartemis.bat, etc): set Path=C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem set Path=%PATH%;C:\strawberry\perl\bin;C:\strawberry\perl\site\bin;C:\strawberry\c\bin;C:\strawberry\c\bin\gnuplot\bin; Hope that helps -- and please let us know! --Matt
