If you have issues installing the Creative Cloud desktop app, please refer to the troubleshooting guide below or submit an RT ticket to receive assistance.
To avoid that, please install and sign in to the Creative Cloud desktop app using the instructions for UMBC owned computers here. This means you likely have the old UMBC Adobe license installed (didn't require you to be signed into your UMBC Adobe account to use), which will cease to function without the Creative Cloud desktop app. If you don't have the Creative Cloud desktop app and are not signed in to it, you will receive an expiration notice, a message to buy a license, a sign in prompt, or a message about a serial number when you open up any Adobe app (do not sign in to the app as it won't properly license). For UMBC owned computers: If the Creative Cloud desktop app is already on the computer (it is named Adobe Creative Cloud and can be found in either the Desktop or Start Menu in Windows or the Applications folder in Mac), you must sign in to it as outlined in the installation instructions for UMBC owned computers here.
