Why won't my Activation Key work?

If you have any difficulties with the licensing or installation of System Mechanic Ultimate Defense:

• Ensure that your computer is connected to the internet and that no firewall, security, or parental control programs are blocking outgoing access.

• Double-check the values you entered for the Activation Key, making sure that no spaces are entered and that all letters and numbers are entered exactly as shown.

• Some characters in the Activation Key (such as the number 0 and the letter O) can look very similar. Try double-checking the following: the letters O, l (lower-case L), I (capital i); and the numbers 0 (zero) and 1 (one).
