I'm sorry for the spam, but I'm out of ideas. I've been stuck in basically the same place for 2.5 days and I can't take it.
I see no mention on server 2003 being compatible with the oracle 12c client here on the oracle website. BUT, i also don't see that it's definitely not compatible. I've tried various google search fixes, [reboots, editing installer ini's to point to x86, etc] to absolutely no avail. All I get are user permission errors [i'm an admin], along with the default environment-related error messages everybody else sees as well.
I'm wondering if I'm wasting my time. I'll take any answer, as long as it's true.
Thanks ya'all.
