I have an Excel 2010 spreadsheet which I need to print to PDF. There is a simple "Save as" PDF option which always fails with just the message "Document not saved". I created a simple test sheet with just a few numbers on to check it isn't due to complexities with the particular workbook. This works on my home PC (Windows 7) but not on the Windows 7 Club PC which is where I need to run it to generate the output which eventually will go to the club's website.

It also fails the same way if I try to create an XPS file (although I don't want an XPS file).

This fails from the normal user interface "Save As". I also tried it from a VBA macro and run it: I get
Run-time error '-2147467261 (80004003)' Document not saved

I've googled endlessly but all the references I tried failed to uncover a solution. I was a bit surprised that this doesn't seem particularly common and most of the reports seem to be a couple of years old or older (no workarounds were useful).
