Once you have a legitimate key (either from purchase or the free trial), here is how to activate it:

If you get an error saying "Invalid license," double-check that you typed it exactly (watch for zeros vs. the letter O). If it says "Blacklisted," you have a cracked key—delete it immediately.


A: No. Legitimate new Supremo license keys are paid software licenses. While Supremo offers a generous free version for personal (non-commercial) use, commercial users must pay. Be extremely wary of "free key generators"—they are always scams or virus vectors.

Using a "cracked" or stolen key is dangerous. Not only does it violate the End User License Agreement (EULA), but it also exposes your system to malware. Hackers often embed keyloggers and backdoors into keygens. Therefore, sourcing a new Supremo license key from an authorized channel is non-negotiable for security.

A: Your key remains valid. However, you must deactivate the license on the old Windows installation before formatting (if possible). If you forget, the activation server might lock the key. In that case, use Supremo's "Reset License" tool on their website or contact support with your purchase receipt.
