"Your license key is not compatible with this version", why?

There are three reasons:

1. If you are using it on Apple Silicon M1 Mac, you need to purchase a new license key which supports Apple Silicon M1 Mac.

2. If you are using it on another Mac, you need to purchase a new license key, because the activation is bundled with the hardware, it is why we state M3 BitLocker Loader for Mac is one license for one Mac at the purchase page.

3. If you are using it on the same Mac, please see below FAQ to find the solution.

FAQ:

Q: I have a lifetime license, why did I receive the above message after updating to the latest version of M3 BitLocker Loader for Mac?

A: The lifetime license is only for the version you purchased, doesn't enjoy major upgrade, check it from the licensing FAQ. If you have not updated to macOS Big Sur, you can still use the old version, even lifetime. If you are using macOS Big Sur, you need to upgrade your license.

Now there is a chance to pay for the difference between lifetime license you purchased and "lifetime license + lifetime upgrade" version and enjoy free upgrade in future version. To purchase the upgrade, please contact [email protected] with your purchase email address and the previous order ID.
