If you can't open a Blackboard assignment file that your lecturer has uploaded, first check that you are using a supported web browser and operating system for the current version of Blackboard.
You may not have the right software or software version installed to open a file of that type. ITS can help you troubleshoot the issue and download the programs you need if necessary. They can also check the assignment file to make sure it hasn't been damaged:
