3. Acquiring a license key (if you have purchased an annual license)

*The license key is valid for one year from the time of acquisition (initial registration of the license acquisition code).
If you purchase a new license to use a compiler for a second year, for example, we recommend only acquiring a new license key when you need to use the compiler again after the first license has expired or at the time the first license expires.

If you have purchased a permanent license, make sure you have the license-key certificate that came with the compiler package.
If you have purchased an annual license, make sure you have the license key you received through step 3, Acquiring a license key.
