DB2 software

I've been trying to download a DB2 environment to use with Visual Cobol 2.3, I tried using the Visual Server and it doesn't work, I unzip the files and run setup and it stops loading with an error.  I tried using IBM DB2 the free version and using director it tells me I need to load Java, which I did and it keeps telling me to load the new Java, when it has been installed successfully.  When I try to download the http version, I just click on RUN and nothing happens.  Is there a DB2 environment that works out there??  HELP!!
