I see, thank you,
will try to look into it when I have a chance.
So far failing to run BTB Editor at my work computer under Windows XP it only works with Windows7 x64 on my home laptop.
Installed .NET 4.0 as Olly suggested but it still doesn't work.
I asked a programmer from our work to run it in his computer, he has newest possible .NET and Visual Studio and Windows XP. It still says 'Isn't a valid Win32 Application'.
Any ideas what else I can fix? I doubt I will have much chance to edit in BTB when at home :p
BTB Editor isn't a necessary tool as one can use BTB-XML, but seems very handy for placing enemy troops with right coordinates on the map.
