After the evaluation period has expired, you will be prompted to enter a license key. If you have purchased the product you will have received a new license key. Enter the purchased license key when prompted to unlock the full "unlimited" version of the software. To take advantage of complimentary email support for up to 30 days, your license key must be registered. If you purchased the product from the VMware Online store, your license key is automatically registered. If you purchased from a reseller, you need to manually register your license key in My VMware. Please consult this KB article for detailed instructions on license key registration.
