Error 26005 when installing Presentation Server 4.5

Hi, I got this error when I tried to install Presentation Server 4.5 64-Bit with Oracle Data Store.
In the midst of the installation process, this error message appeared: “Error 26005.
Could not start IMA service in CTX_IMA_ StartIMAService State = 1.
Clicking OK didn’t help at all. So I am asking our Experts here to kindly please send some help.
Thank you.
