This often has something to do with your web browser. Try using another browser like Chrome or Firefox. You can use the following links to download another browser.
Note: Microsoft Internet Explorer is no longer recommended.
If you still can't download a file, try right-clicking on the file and selecting 'Save As' (or something similar - it depends on your web browser). That should start the file downloading to your computer.
If you still can't open a file, it's usually because you don't have the proper software installed. For example:
- PDF file requires a PDF Reader such as Adobe Acrobat Reader
- DOC and DOCX require Microsoft Office or Open Office
Please make sure you have downloaded and installed those programs before attempting to open a document.
