Could not find an ICA file or Appsrv.ini entry corresponding

Hi there,
I am seeking help for one of the error message which I am prompted for a few days now. Whenever I try to access the Citrix Metaframe presentation server, I am prompted with an error message.
I have tried changing the ICA files but still the same. I am not that aware of the application, so if someone has faced this error message please let me know a solution.

Error number 2323
ICA Client Configuration Manager: Could not find an ICA file or Appsrv.ini entry corresponding to (notepad). Please check your installation, or contact your administrator.
