problems about 2D median filter

Hi,

Using median filter need to install the suite Megacore Function?.

I try following the 2d median filter[/b] v1.0.0 megacore function release notes.[/b] (http://www.altera.com/literature/rn/rn_2dmedian_100.pdf?gsa_pos=2&wt.oss_r=1&wt.oss=median%20filter)

However, when reach the installer source directory. It says need the window installer directory to proceed. I thought all the files should be save in the quartus folder?

Can anyone gives me some advice on this as i could not proceed my project now.
