--- Comment #9 from Austin English austinenglish@gmail.com 2010-12-21 17:15:13 CST --- I've added support for this to wisotool. In short, the workaround I found is to mount both dvd's, copy their files to a folder. Then mount disk 2 (or put the real disk in the drive). Run the installer from the folder on your hard drive, and proceed as normal.
The msxml4 bug is bug 25575. I also filed bug 25576, bug 25577 and bug 25579.
