The installer program contains a few things that may or may not be redistributable - for instance, it contains MSVCRT40.DLL and MFC40.DLL, both of which are available for free from dll-files.com so it seemed to make sense to include them.
You can't redistribute them, unless you have some sort of special license from m$. There is a simple trick to get round this. You can usually find m$ dlls like mfc, msvcrt and so on in microsoft trial game installers. So, to do this legally, you would have to ask the if he wants to accept the license conditions of the trial game that contains the needed dll, then download the demo from the net (You can even point to download.microsoft.com), extract and install the dll (Installing the game may be necessary if you can't get the dlls out of the installer), and then do whatever else the script does. I suppose it would be a good thing to warn the user that he must have a windows license to use IE4,5 or 6.
Do people think this should be linked to from WineHQ?
Not as it is now, M$ could sue for copyright violation, it wouldn't be a nice experience.
