Is it possible to set an Excel file so it can't be saved by the user? Can't
be saved locally or anywhere else?

In a word, NO.
You can get cute with a "Before Save" macro that will shut down the book, or
erase things, or a pop-up saying "If you continue you will be reported", etc,
etc, but it is only good if the user originally "enabled macros" when
starting the file.
You cannot "legislate" integrity.
Maybe a .pdf conversion is the thing for you to use in this case.

Save it as a template. with an XLT file extension, in a read only folder.
That way when the user opens it, it is an XLS file, and has a serial number
tacked on the end.
When the user saves it, it has a new name file1.xls, file2.xls etc.
Your original file isn't damaged. Safe.
But it doesn't prevent the user from having a copy.
If this is OK for you, watch out for some confusion if you have filenames
that already have numbers
such as :
"Budget v.1.xlt", this will become "budget v.11.xls"
Likewise
"Budget March 2006.xlt" will become "Budget March 20061.xls"

If you want to pursue Chuck's points further, here's a link to a site
which gives a way of forcing a User to enable macros:
http://www.danielklann.com/excel/force_macros_to_be_enabled.htm
However, what is to stop a User using Windows Explorer to save a file
onto some removeable media?
Hope this helps.

Note that Daniel's technique, while an excellent method to prevent
accidentally opening the file with macros disabled, isn't designed to
keep even the moderately curious from bypassing the "force" entirely...
- Since he didn't recommend protecting the code from viewing, it would
be trivial for a user to delete the protection in the VBE.
- Even if he had recommended protecting the code from viewing, bypassing
that protection is fairly trivial.
- If the user saves the file, then closes it without saving, the file
can then be opened with macros disabled, and all working sheets will be
displayed.
The latter, of course, would be mitigated if you had code to prevent
saving, but the first two are deadly if you want to really keep someone
from bypassing your restrictions.

Actually, Daniel's code calls HideSheets in the Before_close event. And that
routine saves the file.
Personally, I think that this is just as bad (maybe worse). If the user opens
the file and makes some disasterous changes and wants to close without saving,
the user would have to know how to avoid that event. And if the user doesn't,
the file may be ruined.
And if the user knows enough to avoid the event, then it wouldn't be too much of
a stretch to see how the whole routine could be bypassed.

Nope ... the lazy.
You just need a lock that's better than your neighbours to avoid burglaries
of your place.
