Yes, it's most likely that you're not installing using the Y2K compilant installer.
You need version 3.3.1.1.0C or above I believe to aviod that error.

Oracle no longer have it on Metalink... I have a copy here, but it's about 3Mb. I meant to upload it to a website, but haven't had a chance. I will try and get round to doing this tomorrow anyway.

Sometime setting the system clock back to 1999 works (sometimes it also need a reboot to force it to work) - but this doesn't seem to work all the time.
