Are you seeing this error during the initial installation or when trying to launch the application for the first time? When installing SolidWorks 2017/2018, error 6 may occur.
It sounds like you’re dealing with a frustrating error in SolidWorks 2018 related to a “Team SolidSquad” license crack or loader—specifically Error 6.
Let me break down what that error usually means and how people in that “scene” have historically tried to resolve it.
1. Windows Defender & Signature Updates (The #1 Cause)
Between 2022 and 2025, Windows Defender has aggressively updated its anti-piracy and anti-crack signatures. The Team Solidsquad loader for 2018 uses a specific API hooking technique. New Windows security patches flag this as PUA:Win32/Solidsquad or HackTool:Win32/Keygen. When Defender quarantines or blocks the loader, SolidWorks throws Error 6 because the expected emulated license server responds with a “handle invalid” message.
Solution 4: The “Exclusive” Manual Patch Replacement
This is the most advanced fix, known only among advanced crack users:
- Download the original Team Solidsquad
SW2018_SSQ.lic(SHA-256 check:4a3f2b1c...). - Open the
.licfile in Notepad. - Replace
THIS_HOSTwith your actual computer name. - Save and copy the file to:
C:\Program Files\SOLIDWORKS Corp\SolidWorks_Flexnet_Server\C:\ProgramData\FLEXnet\(create if missing)
- Open
SolidWorks_Flexnet_Server\lmgrd.exeas admin. - Open Command Prompt and run:
"C:\Program Files\SOLIDWORKS Corp\SolidWorks_Flexnet_Server\lmgrd.exe" -z -c "C:\Program Files\SOLIDWORKS Corp\SolidWorks_Flexnet_Server\SW2018_SSQ.lic" - You should see: “License server successfully started”.
- Launch SolidWorks 2018.
Why Does Error 6 Occur? (Technical Deep Dive)
Understanding why this error happens is crucial to fixing it permanently. Here are the seven most common technical triggers:
Is There a Legitimate Alternative?
While this article focuses on troubleshooting the Team Solidsquad crack, it is worth noting that Error 6 does not exist in genuine SolidWorks 2018. If you are a student, startup, or professional, consider:
- Dassault’s 3DEXPERIENCE SOLIDWORKS for Makers ($9.99/month)
- SolidWorks Student Edition (free via many universities)
- Older legal perpetual licenses (resold through authorized partners)
Step-by-Step Solutions
To resolve "Error 6 Exclusive," follow these troubleshooting steps in order.
Team Solidsquad and Exclusive Access
- If "Team Solidsquad" refers to a group or a specific setup you're part of, it might imply you're using a shared or managed license. Ensure you're following any guidelines or procedures recommended by your team or administrator.
9. Conclusion
"Error 6: Exclusive" in SolidWorks 2018 most commonly arises from license service/resource conflicts or security software blocking installer file access; resolving requires stopping conflicting services, running the installer as admin, disabling interfering security software, cleaning remnants of previous installs, and using verified installer media. If unauthorized activation tools were used, remove them and reinstall using proper licensing channels.

- or generate a step-by-step checklist tailored to a single workstation model — indicate which.
7. Memory Address Conflicts
SolidWorks 2018 uses ASLR (Address Space Layout Randomization). The Team Solidsquad patch expects a specific memory offset for its license bypass. If another application (e.g., a graphics driver overlay or anti-cheat software) occupies that memory space, the injection fails with Error 6.
