 I am trying to print a document. When I click the download button there is a
 message that says that Windows cannot print the document because of an
 unknown file type. After the name of the document there are 4 letters which
 are xlsx. How can I find the right program that created the file?

.xlsx  should open with Microsoft Office Excel or can also be read with Excel Viewer

You could also download OpenOffice, which will open most Microsoft Office files.
