what is the error suggest and what is the fix? i uninstall and reinstall still not work. i download 10g_win32_db.zip then extract to d:\oracle, then use the setup.exe from D:\oracle\Disk1 to start install. Could someone tell me what log file i should check to find the possible errors? thanks Received on Mon Nov 01 2004 - 15:11:15 CST
