Many dll dependencies, how to put them in a subfolder ?!

Hi,

I've created a setup project using VS2008. All fine so far. My program is using a bunch of dll's
which are in the same install folder as the executable file. My wish is to put all these dll's into a
"lib" subfolder, but had no luck so far.

In my startup project I already added the reference path to the "lib" folder where all used dll's
are inside... but the program's still crashing. What do I have to do to get my references into that
subfolder ?!

hope you understand what I tried to express :)

bye & thanks in advance :)
