I think the problem is that the user cannot install software globally, 
so cannot install software into the existing Windows installation. 
Another approach could be to package the application using a 
virtualiazation tool such as thinapp so that the DLL files appear to be 
installed globally. Thinapp allows you to create packages that link to 
other packages, so you can have one package for Qt shared with your 
application package.

On a related note, it would be nice if Nokia provided a standardised Qt 
redistributable package for Windows. Now that Qt is LGPL there should be 
no problem with this.
