Virtual Den works with Windows and Mac machines, it has MS Access 2016. The IT people should be able to help you if you have problems. A note - this system (working in the 'cloud' on a 'virtual machine') does not have permanent storage, so you need to save any work you do on YOUR machine before you log off.
Quote from IT person: "I believe this may be a case where they are trying to access the virtualden
from the Citrix Workspace Application and not going to the website
"https://appstore.uky.edu". If you start the application in a 'stand alone'
situation (without it being initiated by the website) it asks for credentials.
Going through the URL https://appstore.uky.edu always
works and I am able to start the VirtualDen Desktop."
