Do a google search for the DX9 "Redistributable". It does exist.
IE6 is a bit more difficult, but there IS a way. I think it's on the
corporate download site, but if you have access to a Windows 9x machine
(this will not work with Win2K or XP machines), you can do this...
It's been a while, so my instructions might be sketchy...
With the Win9x machine, go to the IE site. Download the snippit-installer
onto this machine.
Create a folder on the Win9x machine called "MSIE 6 All OS"
Run the snippit installer.
When you come to the options screen, you want to go to advanced options, or
whatever they call it. Again, it's been a while.
Choose the "Download Only" option, and select all of the OS's near the
bottom (might as well get them all).
Point it to the "MSIE 6 All OS" folder you created on the desktop.
Start the download.
When you are done, you will have a (mostly) complete offline MSIE 6
installer for all OS's in that folder.
Be advised, even with the entire thing downloaded, you almost always still
need an internet connection because some little piece of code has changed
and it wants to go out to the net and grab it.
There are also full MSIE 6 installers on the TechNet CD's if you have access
to them, and it may also exist on the corporate download site at MS.
Unfortunately, I forget the url because I get it on TechNet monthly and
haven't had to use it in a long time.
