If KMSPico fails to activate your software, there are a few steps you can take. First, ensure you have the latest version of KMSPico. Sometimes, software updates can impact activation processes. Next, disable your antivirus temporarily, as it might interfere with KMSPico’s functionality. If it still doesn’t work, you may want to consider other activation tools or, ideally, purchasing a legitimate product key to avoid potential issues and ensure a smooth user experience.
