A simpler method is to make sure that MSXML 6 is installed under Add/Remove programs. It is probably already installed and that is causing the problem. Otherwise install it from Microsoft's website. It is free.

Then in the directory where you have all the install files, find setup32.ini. Make a backup copy of this just in case.

Then edit the original using notepad. Use find to locate the [MSXML] section.

Insert a semicolon at the beginning of the two entries showing the EXE locations. This makes them comments and they will be ignored. Save the file and exit.

Rerun setup.exe and it should work. It did for me.
