Error with downloading SAP

Hi! I am a 3rd year accounting student trying to install an SAP gui onto my brand new Macbook Air. Every time I download the app, it refuses to open and pops up with this error.

"CODESIGNING 1 Taskgated Invalid Signature"

I have Java installed for it and have followed my professor's directions, so it should be working. Can someone help me?
