Can you find some error message? From deep down in my memories I recall that some 8i installer was built for WinNT4 and it complained for not having at "least service pack X". You can try if - ignoreSysPrereqs works Regards, Yavor Ivanov From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Eugene Pipko Sent: Thursday, February 19, 2009 7:58 PM To: 'oracle-l@xxxxxxxxxxxxx' Subject: 8.17. on Win2000? Hi all, Could you please tell me If oracle 8.1.7.4 can be installed on Win 2000 or where I can lookup that information? I tried installing it, but installer (gui) won't start. I googled it and found that I have to rename symcjit.dll That didn't work either.
