To unlock a demo, Email BOTH the MID and Site codes that appear on the opening screen.
(You will receive different for a purchase of Machinist's Calculator for PDA)

Please note that each code will unlock only the computer from which the Computer Identification Code was taken.

The above procedure must be followed for all computers on which the software will be registered.

Because the codes are for specific computers, please label them, for example:

Computer #1: MID: ****-****-****-**** Site: ********

Computer #2: MID: ****-****-****-**** Site: ********

We will send the unlock codes by reply email within two business days.
We will label the unlock codes the same way you label the MID and Site codes.
