Anna,
No, it will work on any computer that has it.
Use selfcert.exe which is (probably) installed on your computer.

Just a question about digital sigs -

I do not have a digital signature, but I've seen some information on
creating my own. If I did create my own signature, could I email this
signature to everyone who would want to use the spreadsheet? Or will the
sig
only work on my computer?
