The type of dongle you are emulating (e.g., HASP, Sentinel).
This feature creates a potential security vulnerability as it allows the system to run unverified kernel code. It is recommended to enable TESTSIGNING OFF via Command Prompt if you no longer need to modify the driver configuration, though the driver may stop working if you do so.
Modern 64-bit editions of Windows (Windows 10 and Windows 11) reject drivers that lack a digital signature verified by Microsoft. Since MultiKey 18.1 is an unsigned emulation driver, you must bypass this restriction. Method A: Advanced Startup Options (Temporary) multikey 181 x64 install
Windows blocks unsigned drivers like MultiKey by default. You must disable this restriction permanently or temporarily.
整个安装过程的核心原则是： Windows x64 系统默认只允许加载有有效数字签名的驱动程序，而 MultiKey 作为一个模拟器，其驱动不具备有效微软签名，因此在常规模式下安装会报“Devcon Failed”错误。下面的步骤专为解决此问题而设计。 The type of dongle you are emulating (e
If the installation still fails, you may need to force-disable the enforcement via the Advanced Startup options:
Restart your computer to ensure the emulator recognizes the new license. Troubleshooting Common Issues Modern 64-bit editions of Windows (Windows 10 and
The MultiKey 18.1 x64 driver package files ( multikey.sys , multikey.inf , multikey.cat ).
Installing this emulator on modern 64-bit Windows systems (Windows 10/11) typically requires bypassing driver signature enforcement to allow the virtual driver to function. Open the Command Prompt as an Administrator .
This error indicates that the driver installed successfully, but it cannot find the structural registry data it needs to boot.
