Mastercam | Virtual Usb Multikey Not Working !new!

This issue is typically caused by Windows blocking the unsigned virtual driver or a recent update revoking its security certificate. The "Virtual USB MultiKey" often appears in Device Manager with a yellow exclamation mark and an Error Code 52 (signature verification) or Code 39 (driver corruption/missing). 1. Disable Driver Signature Enforcement (Primary Fix)

Modern Windows versions (10 and 11) strictly require digitally signed drivers. Since MultiKey is often unsigned, you must bypass this: Permanent Bypass (Test Mode): Open the Command Prompt as an Administrator. Type bcdedit -set TESTSIGNING ON and press Enter.

Restart your computer. You will see a "Test Mode" watermark in the corner of your screen, but the driver should now load correctly. Temporary Bypass:

Go to Settings > Update & Security > Recovery > Advanced Startup > Restart Now.

Select Troubleshoot > Advanced options > Startup Settings > Restart.

Press F7 to "Disable driver signature enforcement". Note: The driver will stop working again once you restart normally. 2. Manual Driver Signing (DSEO Tool)

If Test Mode alone doesn't work, you can manually "sign" the file using a third-party tool:

Download and run the Driver Signature Enforcement Overrider (DSEO) as an Administrator.

Select Sign a System File and enter the exact path to the driver, usually C:\Windows\System32\drivers\multikey.sys. Reboot your system to apply changes. 3. Resolve Driver Conflicts Virtual Usb Multikey Windows 10 Mastercam - Google Groups

Body:
Hi everyone,

I’m having trouble getting the virtual USB Multikey driver to work with Mastercam. I’ve followed the usual steps (disabled driver signature enforcement, installed the Multikey device, replaced the .reg file, etc.), but the license still isn’t being detected.

Here’s what I’ve tried so far:

• Ran install.cmd as admin
• Manually added the driver via Device Manager → Add Legacy Hardware
• Disabled Secure Boot & UEFI (using legacy mode)
• Tried different USB ports and regenerated the licensing files

I’m on Windows 10/11 (specify your OS) and using Mastercam [version]. The Multikey device shows up in Device Manager, but with a yellow exclamation or as “HASP Key not found.”

Any suggestions on what else to check? Could there be a conflict with antivirus or Windows updates?

Thanks in advance.
