Run .ica file for Citrix website

Try downloading the free Citrix Receiver (Mac OS X version) and install, then use Safari with the URL for secure access...you may need to import certificates into the Keychain Access Utility. Works for me for accessing a secure remote desktop.

I don't know how to open the files using the safari browser yet but I have found that when I use chrome, it works, I don't get the "can't open .ica file" message.
