Include .dll in nsis .exe

Hi,

I have two issues :
1. I want to attach an external .dll to the .exe nsis creates.
And i'm not intent to call functions from it -only to have it when I install something on client host - Is it possible ?
2. When I'll have the .dll during the installation - i want to copy it to some folder - how can I perform it?

Thanks!

You do it just like you copy any other file, with the File command.
