Security FAQs

I am getting a warning from Windows Defender SmartScreen when installing.

▼
You can click on "More info" and then "Run anyway" to bypass the warning. This is a common issue with new applications that are not yet recognized by Windows Defender SmartScreen. And it costs extra money to get a code signing certificate in order to avoid this. Rest assured that 16x Prompt is safe to use. If you are still facing issues, feel free to contact us .

You may encounter "The procedure entry point DiscardVirtualMemory could not be located in the dynamic link library" error on Windows 8. This is because the underlying framework for the app no longer supports Windows 8, in line with end of support for Windows 8 from Microsoft. You can try to upgrade to Windows 10 / Windows 11 or use a different machine with Windows 10 / Windows 11. If you are unable to upgrade, feel free to contact us for a refund.
