What it does
Activates this computer with a licence key issued by MET (for example MECHCAD-XXXXX-XXXXX-XXXXX-XXXXX). The licence determines which Edition you can use. You can change Edition later without changing the key.
Where to find it
- The Welcome window (opens automatically when there is no licence yet)
- Help › Activate License (online)…
- Click the Edition badge at the top right of the window (for example ● MECHCAD Premium · Perpetual)

Steps
- Open the Welcome window.
- Enter Full name, Company and E-mail. The e-mail must match the one MET used to issue the key.
- Enter the key in the Licence key (if you have one) field.
- Click Activate licence key (or press Enter in the key field).
- When activation succeeds, the window closes and the badge at the top right shows your Edition.
