Check here for the latest available version of ArcGIS as well as the version currently available on the library computers. While recent, previous versions should work without a problem, you might consider upgrading to the current version, which will be available in the ArcGIS folder on the S drive's Public drive.
Myrin Library Computers are currently running ArcGIS Desktop 10.7.1 and ArcGIS Pro 2.4. While it is possible to save files to be opened in an earlier version, it is simplest to not switch versions. If you plan to use both Ursinus computers and your own computer, install the latest version to your machine.
