What version do you have?
The version of calculator I have, Windows98, works for 8 Hexadecimal digits
(32bits, Dword).

There's a good _free_ program named Calc98 that works with up to 12 Hex
digits (48bits) @
http://www.calculator.org

I don't know of any calculators that work with 16 Hex digits (64bits) but,
there must be some out there.
