I installed a green version of excel2003 some time ago, now the nightmare comes to me. regardless if excel2003 been removed, many application always create the folder named "excel2003" and put a lot of files into it. I can't judge if they can be deleted, and I'm still keep to not touch them. the folder just in "C:\Program Files\excel2003" before, but today I find it in my document folder too, what can I do for it? why it is like this?
