Incompability between O8 and Dev2k

I intalled both O8 enterprise and Dev2k for NT. Dev2k 1.4 comes with Form4.5. But when I try to connect to local oracle, I can not logon using
system account. The error is" no interface driver". But Sqlplus8 works fine, I compiled some
OCI exaples coming with o8, it works fine too. I noticed Form4.5 comes with some old dll
such as ociw32.dll with date of 1996 and ociw32 shipped with o8 is dated in 1997.

Thanks for any help.
