WHERE DO I FIND THE MACHINE ID?

The MACHINE ID is supplied by the software you're going to activate.
Do not insert an arbitrary string or the activation won't be valid.

Launch the software, wait until you're prompted to insert your license and enable the MANUAL ACTIVATION.
If you don't see the checkbox for enabling the manual activation, the software should detect the off-line status automatically and show the manual activation page.

At this point the MACHINE ID is generated and becomes visible. Copy and paste it into this form, then add a valid Computer Name and click CREATE NEW ACTIVATION.

For more details, please consult the user's manual of the software you're trying to activate.
