Those would be system files, on the NT machine, just as it warned you.
The files you brought, it should be obvious, came from an XP machine, and
therefore installing them on NT may actually destabilize the whole system.
There is a concept known as "backward compatibility" which is fairly well
respected in Windows. When new platforms are created, there are some allowances
made for the ways in which older applications were written. Programs created
on NT should run on XP. But it's not possible to insure "forward compatibility"
without having advance knowledge of the future.
All in all, you've quite possibly screwed up the NT system itself,
not just the program you attempted to install.
If you want to create programs which work on multiple platforms, then you
should do your production compiles, and build all your installation sets,
on the OLDEST of the platforms you intend to support. You can safely
package older system libraries in your installer, and when installing on
a newer platform it won't bother to copy those. Going the other way fails
too often to be worth the effort.
