Mastercam X7-2022 Virtual Usb Bus Error !!top!!

The "Virtual USB Bus Error" in Mastercam (typically appearing as Error Code 39) is most commonly associated with driver conflicts, corrupt Windows profiles, or anti-virus interference between Mastercam X7 and newer versions like 2022. Primary Causes & Fixes

Based on user reports and technical discussions, here are the most effective ways to resolve this:

Windows User Profile Corruption: If Mastercam shows as running in the Task Manager but fails to launch, the Windows user profile may be corrupt.

Action: Create a new Windows user profile and attempt to launch Mastercam from there. If it works, you may need to migrate your data and delete the old profile.

Anti-Virus Quarantine: Security software sometimes flags the virtual USB drivers (like MultiKey or HASP drivers) as a threat.

Action: Check your anti-virus "quarantine" or "history" section. Add the Mastercam installation folder and the virtual USB driver paths to your exclusion list.

Driver Error Code 39: This specific code indicates that Windows cannot load the device driver because it is either missing or corrupted.

Action: Uninstall the existing "Virtual USB Bus Enumerator" from the Device Manager, restart your PC, and perform a clean install of the HASP/Sentinel drivers provided by Mastercam. Advanced Troubleshooting

If the basic fixes don't work, consider these deeper technical steps:

Multiple Instances: Avoid having multiple versions of Mastercam (e.g.,

) open simultaneously if you experience frequent crashes, as this can trigger profile corruption.

Hardware Manager Verification: If the hardware manager shows the USB HASP as working but the software won't fire up, try removing the physical dongle (if using one), killing all Mastercam processes in Task Manager, and restarting the application.

Registry Cleanup: Occasionally, leftover registry keys from older virtual driver installations conflict with newer versions. Use a registry cleaner or manually verify keys under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services. ? Mastercam X7-2022 Virtual Usb Bus Error 39 - Google Groups

Mastercam X7-2022 Virtual USB Bus Error (typically appearing as

a common driver-related conflict where Windows fails to load the device driver for the virtual USB bus, often due to corrupted entries, security features, or signature verification issues

. This error prevents Mastercam from recognizing the software license (HASP/Dongle), effectively stopping the program from launching. Google Groups Common Causes Driver Signature Enforcement:

Windows may block the virtual bus driver because it lacks a verified digital signature or the certificate has been revoked. Core Isolation (Memory Integrity):

In Windows 10 and 11, the "Core Isolation" security feature often blocks older or virtual drivers from loading. Corrupt Windows User Profile:

Repeated crashes while multiple Mastercam instances are open can corrupt the user profile, preventing the virtual bus from initializing. Registry Corruption:

Leftover or incorrect "UpperFilters" values in the Windows Registry can interfere with USB device classes. Google Groups Recommended Solutions

Based on user reviews and technical troubleshooting, these steps are frequently successful: Disable Core Isolation: Navigate to Windows Security Device Security Core Isolation Details Memory Integrity and restart your computer. Modify Windows Registry: and navigate to:

Fixing the Virtual USB Bus Error in Mastercam (versions X7 through 2022) usually comes down to a conflict between the HASP driver and your Windows environment. 🛠️ The Quick Fix: Clean & Reinstall

Most "Virtual USB" errors happen because of leftover registry fragments from old drivers.

Unplug your Dongle: Remove the physical USB key from your computer. Mastercam X7-2022 Virtual Usb Bus Error

Run the Utility: Download the HASP User Setup (haspdinst.exe) from the official Sentinel website. Command Line Wipe: Open Command Prompt as Administrator. Drag the .exe into the window and add -purge at the end. Example: C:\Downloads\haspdinst.exe -purge Reboot: Restart your PC to clear the cache.

Reinstall: Run the driver installer again without the purge command. 💻 Fix Windows Driver Signature Issues

Mastercam X7 and older versions often struggle with Windows 10/11 Security.

The Problem: Windows blocks "unsigned" virtual drivers used by older HASP systems. The Fix: Hold Shift and click Restart.

Go to Troubleshoot > Advanced Options > Startup Settings > Restart. Press F7 to "Disable driver signature enforcement."

Try launching Mastercam. If it works, you may need a permanent workaround or a driver update. 🔍 Check for Emulator Conflicts

If you are seeing "Virtual USB Bus" errors specifically, it often means the software thinks there is a pirated emulator installed, even if you have a legal key.

Check Device Manager: Look under "Universal Serial Bus controllers."

Delete "Virtual USB MultiKey": If you see this entry with a yellow exclamation mark, right-click and Uninstall it.

Registry Cleanup: Search for "MultiKey" in your Registry Editor (regedit) and remove associated keys. 🛡️ Antivirus & Firewall

Sometimes your security software flags the license service (hasplms.exe) as a threat.

Whitelist the Port: Ensure Port 1947 is open in your Windows Firewall.

Exclude the Folder: Add C:\Program Files (x86)\Common Files\Aladdin Shared to your Antivirus exclusion list. 🚀 Still stuck?

If you’ve tried these steps and Mastercam still won't see your license, it might be time to move from a physical HASP to a Software License (CodeMeter).

3. Primary Causes

Known Limitations & Warnings

  • No permanent fix for X7–X9 on Windows 11 – Mastercam ended support for these versions before Windows 11’s release. The virtual bus error on Win11 is essentially unfixable.
  • Pirated licenses – This error is extremely common in cracked versions that rely on emulated virtual USB buses. Official licenses using physical NetHASP keys rarely trigger this error (they trigger different USB detection errors instead).
  • Windows updates – After every major Windows feature update (e.g., 22H2 to 23H2), the error may return. Disabling automatic driver updates via Group Policy helps.

5.1 Recommended Fix (Clean Driver Reinstall)

  1. Uninstall all HASP/License Manager components

    • Control Panel > Programs > Uninstall:
      • Mastercam License Manager
      • HASP Driver
      • Sentinel HASP/LDK
  2. Delete leftover driver files

    • Delete C:\Windows\System32\drivers\hardlock.sys
    • Delete C:\Windows\System32\drivers\aks*.sys (e.g., aksfridge.sys, akshhl.sys)
  3. Remove hidden devices

    • Open Device Manager → View → Show hidden devices.
    • Uninstall any grayed-out “Virtual USB Bus” or “HASP Key” entries.
  4. Reboot and install latest License Manager

    • Download Mastercam License Manager 2022 (v8.0 or later) from Mastercam’s official site.
    • Run installer as Administrator.
  5. Plug in HASP key and test.

Solution 3.2: The Registry & Test Mode Permanence (For X7-X9)

To make the fix permanent for legacy versions:

  1. Open Command Prompt as Administrator.
  2. Type: bcdedit /set testsigning on and press Enter.
  3. Restart your PC. You will see "Test Mode" watermark on the desktop. This allows older drivers to load.
  4. Download the Sentinel HASP/LDK 7.90 Driver (a stable version that supports X7 through 2017).
  5. Uninstall existing drivers via Apps & Features -> Sentinel HASP/LDK.
  6. Reinstall the 7.90 driver.
  7. Run Mastercam.

To exit Test Mode later: bcdedit /set testsigning off


5. Run as Administrator

  • Try running Mastercam X7-2022 as an administrator. Right-click the executable or shortcut and select "Run as administrator."

5.4 Switch to Soft Licensing (if possible)

  • For Mastercam 2021/2022, convert from HASP to CodeMeter (network or software ID). Contact your Mastercam reseller to migrate licenses.
