--- Comment #4 from nightstrike@gmail.com 2013-03-22 13:04:41 CDT --- For reference, when I install office or visio on a clean prefix, I use winecfg to set msxml2, msxml6, and riched20 to native,builtin. I don't use winetricks for anything, because it always breaks.
The takeaway is that both prefixes are configured the same.
I will add msxml3 to the winecfg list.
