This report aims to provide an overview of the error, its causes, and possible solutions.

Error Description

The SSQ Error 6 is an activation error that occurs when trying to activate SolidWorks 2018 using the SolidWorks Activator tool. The error message typically reads:

"Error 6: The activation request failed. Please contact your system administrator or SolidWorks support."

Causes of the Error

Several factors can contribute to the occurrence of SSQ Error 6:

1. Incorrect Installation: Incomplete or corrupted installation of SolidWorks 2018 can lead to activation errors.
2. Network Issues: Connectivity problems or firewall restrictions can prevent the activation process from completing successfully.
3. Invalid Product Key: Using an invalid or expired product key can cause activation errors.
4. SSQ Activator Issues: Problems with the SSQ Activator tool itself, such as corrupted files or outdated versions, can lead to errors.

Solutions to the Error

To resolve the SSQ Error 6, try the following steps:

1. Verify Installation: Ensure that SolidWorks 2018 is installed correctly and completely. Reinstall the software if necessary.
2. Check Network Connection: Verify that your network connection is stable and that firewall restrictions are not blocking the activation process.
3. Validate Product Key: Ensure that the product key is valid and has not expired.
4. Update SSQ Activator: Check for updates to the SSQ Activator tool and install the latest version.
5. Run Activator as Administrator: Run the SSQ Activator tool as an administrator to ensure it has the necessary permissions.
6. Contact SolidWorks Support: If none of the above steps resolve the issue, contact SolidWorks support for further assistance.

Conclusion

The SSQ Error 6 is a common activation error encountered during the activation process of SolidWorks 2018. By understanding the causes of the error and following the recommended solutions, users can resolve the issue and successfully activate the software. If problems persist, it is recommended to contact SolidWorks support for additional assistance.

Recommendations

• Ensure accurate and complete installation of SolidWorks 2018.
• Verify the validity of the product key.
• Regularly update the SSQ Activator tool.
• Run the SSQ Activator tool as an administrator.

Future Work

Further research is recommended to explore other potential causes of the SSQ Error 6 and to develop more comprehensive solutions. Additionally, it would be beneficial to investigate the effectiveness of the recommended solutions and gather user feedback to improve the activation process.

Step 6: Manual Patching as Alternative to the GUI Activator

If Error 6 persists, the GUI-based offset patching is failing. Use the manual method: solidworks 2018 activator ssq error 6

1. Stop all SolidWorks services (Run services.msc).
2. Replace the license file manually:
   • Copy sw_d.lic to C:\Program Files\SOLIDWORKS Corp\SolidWorks\
   • Edit the lic file to replace SERVER this_host 0073421 with your actual computer name and MAC address.
3. Use the SSQ License Server folder to run server_install.bat as admin.
4. Set environment variable: SW_LICENSE_FILE=25734@localhost

This bypasses the GUI patcher entirely, avoiding Error 6.

3) Network & connectivity checks (for online activation or SNL)

• Ensure outbound HTTPS (port 443) is allowed to SolidWorks activation servers.
• If using a proxy, configure SolidWorks/Windows proxy settings or test on a machine with direct internet to isolate proxy issues.
• For network license manager: ensure client can reach the SNL server on port 25734 (or custom port) and that the SNL service is running.

8) Using SolidWorks Customer Portal & reseller support

• Gather these items before contacting support:
  • Serial number(s).
  • Exact product/version (SolidWorks 2018 SP/version).
  • Full error message and log excerpts with timestamps.
  • Steps already attempted.
• Contact your SolidWorks reseller first (they manage entitlements) or use SolidWorks Customer Portal to open a support case.

Step 2: Disable Real-Time Antivirus and Windows Defender

Even if you trust the SSQ file, Windows Defender’s Controlled Folder Access and Real-time protection will interrupt low-level patching.

1. Windows 10/11: Settings > Update & Security > Windows Security > Virus & threat protection > Manage settings.
   • Turn off Real-time protection.
   • Turn off Tamper Protection (if available).
2. Temporarily disable Third-party AV (McAfee, Norton, Kaspersky, Avast).
3. Add exclusion: Create a folder on your desktop (e.g., C:\SSQ_Patch) and add it to the antivirus exclusion list. Place the activator there.

Root Causes of Error 6

Through analysis of user reports across forums (Reddit, CADTutor, SolidWorks forums), Error 6 emerges from five primary sources:

| Cause | Description | |-------|-------------| | 1. Windows Defender / Antivirus Interference | Real-time protection quarantines or blocks the patcher’s memory write attempts. The activator returns “Error 6” instead of “Access Denied.” | | 2. Corrupted or Incomplete SSQ Download | A single corrupted byte in the SW2018_Activator_SSQ.exe can cause an arithmetic overflow when calculating patch offsets. | | 3. Missing Visual C++ Redistributables | The SSQ tool is often compiled in older Visual Studio versions. Without 2008/2010/2012 runtimes, math operations fail, yielding Error 6. | | 4. SolidWorks Services Partially Running | If SolidWorks Licensing Service or FlexNet Server is stuck in memory, the activator cannot patch the DLL – overflow occurs when trying to write to a protected memory region. | | 5. 32-bit vs 64-bit Mismatch | Running a 32-bit activator on a 64-bit OS without proper permissions (especially from SysWOW64 folder) can trigger overflow errors. |

3. Stop the SolidWorks Licensing Service Manually

• Press Win + R, type services.msc, and press Enter.
• Find SolidWorks Licensing Service and FlexNet Licensing Service (if present).
• Right-click each → Stop.

Prevention Tips

• Always disable antivirus before running any activator — re-enable immediately after.
• Keep the SolidWorks installation path default (C:\Program Files\...) to avoid path-related errors.
• Do not run the activator from a network drive or a compressed (ZIP) folder; extract it locally.

The 3 Most Common Fixes:

1. Run the Activator as Administrator (The #1 Fix)

• Right-click the SSQ.exe or the loader file.
• Select "Run as administrator" .
• Do not just double-click it. Even if your account is an admin, UAC blocks it.

2. Disable Windows Defender / Antivirus (Temporarily) Report: SolidWorks 2018 Activator SSQ Error 6 Introduction

• Error 6 often appears when Defender's "Controlled Folder Access" or "Real-time protection" blocks the crack from writing to C:\Program Files\SOLIDWORKS Corp\.
• Action: Turn off Real-time protection > Apply the activator > Add the SOLIDWORKS folder as an exclusion > Turn protection back on.

3. Manually Copy the License File If the automatic activator keeps failing:

• Locate the sw_d.lic file inside the SSQ download.
• Copy it manually to: C:\Program Files\SOLIDWORKS Corp\SOLIDWORKS\
• Right-click the file > Properties > Uncheck "Read-only."
• Run the SSQ registry patch portion only (if separate).
