We are installing Adobe CC 2020 in addition to the Adobe CC 2019 on all lab machines.
If you have started a complex or thesis project in an Adobe CC 2019 app, it is recommended that you continue to use Adobe CC 2019 until the completion of the project.
To open a project in an Adobe CC 2019 app, right click on your project and select Open with > Adobe CC 2019.
You can also launch any Adobe CC 2019 app and then open your project from within the app.
Be aware that if you double click on your project, it will automatically open in Adobe CC 2020 and may ask you to update the file which will no longer be compatible with Adobe CC 2019.
If you have any questions, please submit a ticket.
