Solidworks 2018 Activator Ssq Error 6 Guide
The "Error 6" encountered in the SolidWorks 2018 SSQ (SolidSquad) activator typically points to a conflict with Visual Basic for Applications (VBA) 7.1 components or an "Access Violation". This often happens when a newer version of SolidWorks (2021 SP2 or later) was previously installed on the machine, leaving behind a version of VBA that the older 2018 installer cannot override. Potential Fixes for Error 6
To resolve this error and successfully activate the software, users and technical communities often suggest the following steps:
Uninstall Newer VBA Components: The most common solution is to manually remove the existing VBA 7.1 files so the 2018 installer can place its own. Navigate to your installation media's PreReqs folder.
Find the VBA folder and right-click to uninstall vba71.msi and vba71_1033.msi.
Run as Administrator: Ensure the SolidWorks 2018 Activator (SSQ) is run with administrative privileges. Right-click the .exe and select Run as administrator.
Data Execution Prevention (DEP): In some cases, Error 6 is linked to an "Access Violation." Turning on DEP for all programs except those you select might bypass this system-level block.
Force Local Activation: Within the SSQ activator interface, use the "Set Serial Numbers" option and ensure "Force Local Activation Serial Numbers" is selected before proceeding with the installation. Official Alternatives
If these community workarounds do not work, it is recommended to use official SolidWorks Support channels. Genuine licenses can be managed and fixed using the SolidWorks Product Activation Wizard, which allows for automatic activation over the internet or manual activation via email.

The SolidWorks 2018 Error 6 typically occurs during activation when using the SSQ (SolidSquad) activator, often manifesting as an "Access Violation" or a failure to obtain a license. This error is frequently caused by residual license files from previous installations, interference from security software, or compatibility issues with newer Windows environments. Core Troubleshooting Steps 1. Clean Up Residual Licenses
Existing license files can cause conflicts with the 2018 activator.
License File Cleanup: Open the SSQ activator and navigate to the Extensions tab. Click Start next to SolidWorks license file cleanup and select standalone license.
Obtain License Fix: In the same activator, locate the option for could not obtain a license for SolidWorks, select your version (2018), and click OK. 2. Security and System Configuration
Antivirus software or Windows security settings often block the activation process.
Antivirus Interference: Ensure that your antivirus is disabled during extraction and activation. Security software may delete critical files from the SolidSquad folder, leading to licensing failures.
Data Execution Prevention (DEP): If the error is specifically an "Access Violation," you may need to adjust DEP settings. Go to System Properties > Advanced > Performance Settings > Data Execution Prevention and turn it on for all programs except those you select, then add the SolidWorks executable. 3. Manual Activation and Registry Reset
If automatic activation fails, manual steps or a registry refresh may be required.
Registry Reset: Corrupt registry keys can prevent the software from launching correctly. Use the Windows Registry Editor (regedit) to navigate to HKEY_CURRENT_USER\Software\SolidWorks and rename or delete the folder to reset settings to default.
Manual Activation: If the internet-based activation fails, you can use the manual via email option. This involves saving a request file and emailing it to activation@solidworks.com to receive a response file. The "Error 6" encountered in the SolidWorks 2018

Title: The Cost of Error 6
Logline: Desperate to meet a deadline, a freelance engineer ignores every warning sign, leading to a catastrophic failure that no patch could fix.
The Story
Alex Vega was a ghost in the machine. A freelance mechanical design engineer, he survived on tight deadlines and thinner margins. His weapon of choice: SolidWorks 2018. His enemy: the $4,000 annual subscription fee.
For two years, Alex had used an "SSQ" activator—a crack named after its legendary Russian source. It was a silent, invisible patch that tricked SolidWorks into thinking it was a legitimate copy. It had never failed him.
Until the night of September 12th.
With 48 hours to deliver a complex injection mold assembly to a medical startup, Alex fired up his workstation. SolidWorks loaded, then froze. A small red box appeared:
"Error 6: License Manager Overload – Invalid Host ID."
Alex frowned. Error 6. He knew the SSQ readme file by heart. "Error 6 usually means the network license manager cannot verify the fake server port. Restart the 'SolidWorks FlexNet Server' service as Administrator."
He followed the steps. Nothing.
He disabled Windows Defender. Disabled his firewall. Ran the activator again. The SSQ patch ran its course, displayed "Success," but when he opened SolidWorks—Error 6.
By midnight, desperation set in. He found a deep thread on a shadowy forum. "Error 6 after Windows Update KB4457122," a user wrote. "Microsoft changed the way the OS handles virtual network adapters. The SSQ activator creates a fake adapter. The patch can't see it anymore."
The fix was brutal: uninstall the Windows update, wipe the registry keys for SolidWorks, and reinstall the activator in "Test Mode"—a stripped-down Windows state with no driver signature enforcement. Turn off Real-time protection
Alex did it. At 3:00 AM, SolidWorks 2018 booted. He exhaled. He finished the mold assembly at 10:00 AM and sent it off.
The cost came two weeks later.
The medical startup called. Their injection molding partner ran a standard pre-production validation. The files Alex sent contained a dormant piece of code—a leftover from the SSQ activator’s modified SW_D.exe executable. It wasn't a virus, but it was a corruptor. It offset every fillet radius by 0.2mm.
The molds were cut. 30 metric tons of hardened steel. $180,000 in machining.
Nothing fit. The plastic parts came out with razor-sharp edges.
The startup sued Alex for gross negligence. SolidWorks’ legal team got involved after they found the cracked license fingerprint embedded in the file metadata. Error 6 wasn’t just a technical fault—it was a tripwire. The newer versions of the SSQ activator had a hidden kill-switch that triggered on specific Windows builds, deliberately corrupting random parametric constraints as a form of "anti-tamper sabotage."
Alex lost everything. His LLC, his workstation, his reputation. In the final deposition, the expert witness said:
"Error 6 is the crack's way of screaming, 'I am compromised.' When you forced it to run anyway, you didn't fix the license. You broke the math."
Now, Alex works at a big-box hardware store. He still dreams in CAD. But every time he reaches for a software license, he hears a whisper: Error 6.
Moral: The most dangerous error isn't the one that stops your software. It's the one you force to run anyway.

2. Disable Antivirus and Windows Defender (Temporarily)
- Turn off Real-time protection.
- Add the entire SolidWorks installation folder and the activator’s location to the exclusion list.
- Re-enable antivirus after successful activation.
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. |
Troubleshooting SolidWorks 2018 Activator — SSQ Error 6
If you’ve encountered “SSQ Error 6” while attempting to activate SolidWorks 2018 with an activator or license tool, you’re not alone. This error typically appears during offline or manual activation attempts and indicates the activation handshake between the client and SolidWorks licensing services failed. Below is a concise, actionable guide to understanding the cause, checking likely triggers, and resolving the issue safely and legally.
Quick checklist (start here)
- Confirm license method: Verify whether your organization uses standalone (serial-based) or network/SSN (Site/SNL) licensing. Activation steps differ.
- Use official channels: Always prefer SolidWorks’ official activation process via the SolidWorks Activation Wizard or your reseller/SOLIDWORKS admin.
- Check files: Ensure the activation request (.REQ/.RRF) and response (.RES/.RSP) files are complete and unmodified.
- Clock & locale: Ensure system date/time and time zone are correct; mismatches can invalidate tokens.
- Run as Administrator: Launch the SolidWorks Activation Wizard or license utility with administrative privileges.
- Antivirus/Firewall: Temporarily disable or add exceptions if local security tools are blocking file creation or license utilities.
- Paths & permissions: Ensure the license folder (usually C:\ProgramData\SOLIDWORKS) is writable and not redirected or blocked by policies.
6. Use the Correct Activator Version
- Verify you are using the SSQ activator specifically for SolidWorks 2018 (not 2019 or 2020). Hash mismatches can cause Error 6.
Summary of Action Plan for Error 6
| Step | Action | Expected Result | |------|--------|----------------| | 1 | Uninstall all SolidWorks components + reboot | Clean slate | | 2 | Disable AV + Defender real-time protection | No interference | | 3 | Verify activator checksum | Ensure file integrity | | 4 | Install VC++ 2008-2022 runtimes | Fix arithmetic dependencies | | 5 | Run as Admin + Win7 compatibility mode | Proper memory access | | 6 | Manual patch via license server files | Bypass the GUI patcher | | 7 | (Last resort) Disable DEP | Allow overflow-style patching |
If you complete all steps and still see “SolidWorks 2018 Activator SSQ Error 6,” the core issue is likely an incompatible Windows build (e.g., Windows 11 24H2) that has removed legacy support for the patching method. No known fix exists beyond reverting to an older OS or purchasing a legitimate license.
What SSQ Error 6 usually means
- The activation service couldn’t validate the activation request due to a malformed or mismatched activation file, missing required files, corrupted request/response, or network/permission issues that prevent proper generation or application of the SSQ (SolidWorks activation) response.
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.
