I think I have a solution for it, I'll upload a fix later today. I'm working on UTF-8 encoding to catch some of the more unusual character names too.
As far as 64 bit versions of Excel being unable to use the battle.net query, I'm afraid that's not going to be avoidable unless anyone can recommend a different way of getting the info. Microsoft haven't translated the function I use here over to their 64 bit version yet, sorry!

I have a German Vista 64-bit and a German Microsoft Excel 2003. When I click on the button, unfortunately I get a runtime error 380 (A script engine for the specified language can not be created.) and I can only debug or close it. Do ya have any idea what can I do?
