Output from 'winecfg' after clean .wine
Fails to load builtin msxml3.dll?
Yes, it's a problem. msxml3 (and msxml4) won't work in Wine without libxml2. Personally I don't know what ELFCLASS64 error means, are you sure you don't run 64bit machine+OS and 64bit libxml2?
You were right - lib32-libxml2 is not a dependency on the wine package in AUR so I was missing this. Installed it, though it doesn't seem to alter the situation. The log I gave you (from setup) still looks exactly the same. Nothing in there hinting at why Office setup would crash?
