Problem in installing Chessmaster 9000

Hi,
I am using windows 98 as OS. My system configuration is as follows:
Hard-disk:160 GB
Processor: Dual Core
RAM: 512MB
A few days ago i faced a problem when i was trying to install the program chessmaster 9000. I got a message like this
"Please login with administrator privileges and try again."
I logged in as administrator but the same message is shown. I was unable to install the program. How can i solve this problem? Please Help me.
