Installing MultiKey 18.1 x64 on modern versions of Windows (like Windows 10 or 11) is a specialized process because the driver is typically unsigned. Microsoft requires digital signatures for 64-bit drivers, so you must bypass these checks to get it running. Installation Steps Disable Driver Signature Enforcement Open the Command Prompt as an Administrator. Run the command: bcdedit -set TESTSIGNING ON.
Restart your computer. You should see a "Test Mode" watermark on your desktop. This is required for the driver to load. Prepare the Driver Files
Locate your MultiKey 18.1.0 (x64) folder. It usually contains multikey.sys, multikey.inf, and a registry file (.reg). Copy multikey.sys to C:\Windows\System32\drivers. Install via Device Manager Right-click the Start button and select Device Manager.
Click on your computer name at the top, go to the Action menu, and select Add legacy hardware.
Choose Install the hardware that I manually select from a list (Advanced).
Installation Guide: MultiKey 18.1.0 (x64) for Windows This technical documentation outlines the standard procedure for installing the MultiKey 18.1.0 emulator on 64-bit Windows systems (Windows 7 through Windows 11). This process is frequently required for software environments utilizing virtual USB dongles, such as SolidCAM or Mastercam. 1. Pre-Installation Requirements
Before starting, ensure all previous emulator versions and conflicting drivers are removed to prevent "Code 39" or "Code 52" errors.
Remove Legacy Drivers: Use a cleanup utility like Infclean to purge old %WINDIR%\INF files from previous MultiKey or VUSBBUS installations.
Disable User Account Control (UAC): Navigate to Control Panel > User Accounts > Change User Account Control settings and set the slider to "Never Notify". 2. Disabling Driver Signature Enforcement
Windows 64-bit systems strictly require signed drivers. Since MultiKey is often unsigned, you must bypass this security check. Option A: Test Mode (Permanent) Open Command Prompt as Administrator. Enter the following commands: bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS bcdedit -set TESTSIGNING ON
Reboot your computer. A "Test Mode" watermark should appear in the corner of your desktop. Option B: Advanced Startup (One-time) Hold Shift and select Restart.
Navigate to Troubleshoot > Advanced options > Startup Settings > Restart. Press 7 or F7 to "Disable driver signature enforcement". 3. Registry Configuration
The emulator requires a "dump" of the physical key to function.
Locate your software-specific registry file (e.g., dump.reg). multikey 181 x64 install
Right-click the file and select Merge to add the emulation data to the Windows Registry. 4. Installing the MultiKey Driver
Locate the Installer: In your MultiKey 18.1 folder, find mkinstall_x64.exe. Execution: Run the installer as Administrator.
If using a command line method, use devcon install multikey.inf root\multikey.
Approval: When Windows prompts that it cannot verify the publisher, select "Install this driver software anyway". 5. Verification
After a final reboot, verify the installation in Device Manager: Look under System devices for "Virtual USB MultiKey".
Depending on the specific key being emulated, you may also see new entries under Universal Serial Bus controllers, such as "SafeNet USB SuperPro" or "HASP Key". Troubleshooting Common Errors
Code 52: The driver was installed but is blocked because it isn't digitally signed. Ensure Test Mode is active.
Devcon Failed: Often caused by trying to install without first disabling driver signature enforcement.
Signing Tools: Use the Driver Signature Enforcement Overrider (DSEO) to manually sign multikey.sys if Test Mode alone is insufficient.
Installing the MultiKey 18.1 x64 emulator on modern 64-bit systems like Windows 10 or 11 requires specific steps to bypass security features like Driver Signature Enforcement , which often blocks these drivers from loading. Pre-Installation Steps
Before starting, you must prepare your Windows environment to accept the virtual driver: Disable User Account Control (UAC) : Set the UAC slider to "Never Notify" in the Control Panel and reboot your computer. Enable Test Mode
: Open a Command Prompt as Administrator and run the following commands to allow unsigned drivers: bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS bcdedit -set TESTSIGNING ON
: You must restart your PC for these changes to take effect; you should see a "Test Mode" watermark on your desktop. Installation Procedure Installing MultiKey 18
Once in Test Mode, follow these steps to install the driver: Remove Old Versions : If you have a previous MultiKey version, run the remove.cmd remove.bat file in your MultiKey folder to prevent driver conflicts. Add Registry Data : Locate the
file for your specific software and double-click it to merge its data into the Windows Registry. Run the Installer : Right-click mkinstall_x64.exe install.cmd ) and select Run as Administrator Confirm Installation
: When a Windows Security window appears stating it cannot verify the publisher, select "Install this driver software anyway" Verify in Device Manager : Open Device Manager and check under System devices . You should see "Virtual USB MultiKey" listed without any error icons. Troubleshooting Common Errors Error Code 39 or 52
: These indicate a driver signature issue. Ensure you are in and consider using a tool like the Driver Signature Enforcement Overrider (DSEO) to manually sign the multikey.sys file located in C:\Windows\System32\drivers\ Driver Not Loading
: If the device has a yellow exclamation mark, right-click it in Device Manager, select Update Driver , and manually browse to your MultiKey installation folder. Conflict with Security Updates
: Recent Windows updates may revoke older certificates. If errors persist, you may need to uninstall recent "Quality Updates" or use a patched version of the driver. Are you installing this for a specific software
