The Cause: Nesmaker uses memory injection techniques to simulate NES hardware. Many antivirus programs (especially Windows Defender) flag this as a false positive.
The Fix: Add your entire Nesmaker folder to the Antivirus "Exclusions" list before you try to activate. If the .exe is deleted, you must reinstall.
The Cause: You are typing the code manually and making a typo. The characters 0 (zero) and O (letter O) look very similar. Also, check for trailing spaces.
The Fix: Copy and paste directly from the Itch.io page. Do not re-type it.
The Cause: You activated Nesmaker, then you upgraded your RAM, swapped your graphics card, or (most commonly) reformatted your hard drive. Nesmaker sees the PC as a new machine.
The Fix: You have two resets per license. Email support at support@thenew8bitheroes.com with your original purchase receipt. They will reset your activation count.
Warning: Do not buy "cheap codes" from eBay or G2A. Scammers will sell you codes from stolen credit cards. When the chargeback happens, Nesmaker's servers will blacklist that key immediately, and you will lose all your projects.

Nesmaker is the revolutionary software that allows you to build actual NES games without needing a Computer Science degree from the 1980s. But like any powerful tool, the key to the kingdom is a unique string of text: the Nesmaker Activation Code.
