Since this is an installation question, I'm assuming it will be something that's been seen before and a technote probably exists somewhere...
I have a new machine -- A celeron 1.8ghz machine with 512mb or ram running xp/home.
I have an Oracle 8i driver CD given me by a client -- I use it to do development work for them, accessing their server from work station when building, then load the application on a server at their site once it works.
When I attempt to install, I never get a dialog box. I can insert the CD, click on install, but the setup dialog boxes offering me a choice of what to install never comes up.
I get the same result running setup from the operating system prompt.
