Oracle Database Express Edition (XE)

Hi,

I'm trying to install Oracle database XE on my system (Windows XP Service Pack 3) and keep getting an error "failed to load dll chkportdl2"" while trying to do so.
While researching on a fix,I came across a solution that suggested uninstall of XP service pack 3 during installation and reinstall later.

Now,I dont see an option for "Windows XP Service Pack 3" in "Add/Remove Programs".
I believe Windows XP OBI comes up pre-loaded with Windows XP Service Pack 3 and am not sure if I can uninstall it.

I looked up some other methods of removal here -

however,they werent very helpful either.


Could you suggest how to fix this problem being faced in installing Database XE.
Thanks and Regards,
