Outlook 2003 creating signature – Word won’t open, Notepad does

Hi all,
I wonder if you could help me out with this. I am trying to create a signature with an image file and I can do it with no problem on outlook 2003 English version – I go to edit signature under formal mail in tool options and MS Word will open and I then edit from there. However, from outlook 2003 Korean version Notepad opens, not Word. I select html as mail version and ticket the bocks ‘open in MS word 2003’, but to no avail. Word won’t open. Can anyone help?
thank you!
