After you login for your first time, you will notice a warning message in the Citrix portlet. It asks you to install the Citrix client because it is required for all the applications within the Citrix section of the portal.
If you need the Citrix client, you can download a copy inside the “Downloads” folder in the Citrix portlet. People who already have the Citrix client installed on their computers (from their workplace, for example) do not need to reinstall the client.
Windows Users: When you launch an application you will get the following prompt. Select Full Access and Never ask me again to have the ability to save and view file on your local drives through the Citrix client.

Mac Users Note:
Though these are Windows programs being launched from the server, the Citrix client is available for the Macintosh and will let you have access to these applications as well.
To set access rights for your client, you need to go to
Applications/Citrix ICA Client and run the Citrix ICA Client Editor
application. Click the Default Settings button.

After clicking default settings, you'll see the drives from your
Mac. The A and B drives would be your floppy and CD ROM drives (if
any), and C will default to the Home directory on your account.

In the read and write columns are icons indicating their status.
An icon with glasses means read permissions, and an icon with a pencil
means write permissions. A red X on an icon indicates that no
permission is given, a question mark indicates you will be prompted when
you connect if you want to give permissions for that session, and no
extra indicator means that that particular right is granted.
