I am doing an install of Netweaver EHP1 ce 7.1 ORACLE (JAVA) on an Windows Server 2003 x64 64 bit machine. I have installed Oracle using sapserver.cmd, but now when I am installing the NW it says that Oracle is not installed. What are some of the troubleshooting methods I can use to fix this? On this server, I need to install everything on the D:\, but I made a mistake by installing Oracle on the C:\. I have uninstalled it from C:\ and installed it on D:\ and rebooted the machine. NW still throws an error. What should I do?
