MSXML SP2 installer +msi trace (lzma compressed)

With wine-1.3.6-240-g791b22a, after running the MSXML4 SP2 redist installer
with default installation settings, the side-by-side assembly files are placed
in "C:\SXS" rather than the expected "C:\windows\system32\winsxs" directory.
This seems to hurt the Flight Simulator X demo, which complains about broken
MSXML4 SP2 installation on startup. The SP3 version of the redist doesn't seem
to have this problem. A +msi trace is attached on the presumption that the
issue is msi-related.
