Greetings To All!

I have been spending the better part of this weekend trying (without any real progress) to install the Oracle Grid Infrastructure on my home PC as a precursor to later installing Oracle 11g Enterprise Database...

The problem I am having is that I cannot seem to get the runInstaller command to execute. I am trying to run this (the runInstaller command) from DVD installation media installed in the DVD drive. The drive is mounted and I am able to successfully access the files in the mount point; but for whatever reason, the runInstaller command will not execute.

Please note that I am logged in as user oracle (as required). I even tried to change the permissions on the runInstaller file so that I could execute the command and the OS would not even allow me to change permissions on the file. I am sure the solution is something probably very simple...but what? Any ideas? Please see down below the commands I ran and their results. Thanks! Rob
