Follow up to bug 5131, FlashFXP's installer quits early, since it can't
register its dll. A 'wineserver -k' will kill the installer, and it works fine,
but if you click ok to the error, it will rollback the changes and uninstall.

points to oleaut32. Indeed, 'winetricks -q dcom98' lets the installer proceed
as normal.
