Hi, Could you please check the link for downloading cilk_8503-i686.release.tar.gz after the license agreement? It shows a filesize 2.16 MB and gives an error on extracting.

My Visual Studio 2008 complains that a file called cilk_1_1-x86.dll is missing. I re-installed Cilk (msi) and the problem still remains. I would appreciate any help.
