6007 Cadworx Link | Error Number

The error number 6007 in CADWorx (typically during setup, installation, or license activation) generally indicates a license or network communication failure.

Common causes and solutions:

  1. License Server Connection Issue

    • The client cannot reach the license server.
    • Check that the server name/IP and port (usually 27000-27009 or 25734) are correct in the license configuration.
    • Verify network connectivity (firewall, VPN, DNS).

  2. Invalid or Missing License File

    • The license file may be corrupted, expired, or not correctly installed on the server.
    • Regenerate the license from your CADWorx provider.

  3. FlexNet License Service Not Running

    • On the license server, ensure the FlexNet Licensing Service is started.
    • Restart the service or reinstall the license manager.

  4. Version Mismatch

    • The CADWorx version may not match the license version (e.g., using a newer CADWorx with an older license).

Recommended next step:
Check the CADWorx License Manager logs or the FlexNet debug log for more specific details. Also contact Hexagon (CADWorx support) with the exact context (installation, launch, or during a command) and your license type (standalone/network).

5. Antivirus or Network Locking

Overzealous antivirus software (like McAfee or Norton) can lock .dwg or .mdb files while scanning them. Similarly, network latency on a NAS or server share can cause timeouts that CADWorx interprets as error 6007.

3. Check File Permissions

  • Right-click the database file → Properties → Security.
  • Ensure your Windows user account has Full Control (Read, Write, Modify).
  • Temporarily disable real-time antivirus (e.g., Windows Defender, McAfee) and test. If solved, add the CADWorx project folder to the antivirus exclusion list.

5. Isolate the Corrupt Component (if error occurs on a specific line/component)

  • Use CADWorx → Isometric → Create Iso on a very small section of piping.
  • If the error appears only when a particular component (e.g., a specific valve or flange) is included, delete and re-insert that component from the spec.

2. Corrupted Specification (Spec) File

Your project's spec file (e.g., myspec.mdb) may have internal corruption—perhaps due to a power outage, improper shutdown, or a failed component edit. CADWorx cannot parse the spec tables, triggering error 6007 when reading dimensions or end types.

Preventing Error Number 6007 in the Future

Once resolved, implement these best practices to avoid recurrence: License Server Connection Issue

  • Always close specs from the Spec Editor – never force-close AutoCAD while a spec is open.
  • Use local copies for editing – keep master specs on the network but copy them locally to edit, then replace the master afterward.
  • Upgrade all users to the same CADWorx version – version mismatch is almost guaranteed to cause error 6007 eventually.
  • Schedule regular database maintenance – use Access’s Compact and Repair on your spec files once a month.
  • Avoid special characters in spec and project paths – spaces, ampersands, and parentheses can confuse CADWorx’s database driver. Use underscores instead.

Resolution & Troubleshooting Steps

Follow these steps in order to resolve the issue.

6. Reinstall or Repair CADWorx

  • Go to Windows Settings → Apps → CADWorx → Modify/Repair.
  • This restores missing registry keys and ODBC connections related to database access.
