9 Ways to Completely Remove SolidWorks from Your System

Published 10 May 2026

Removing SolidWorks from a computer involves more than just clicking 'Uninstall'—it requires addressing residual files, registry entries, and dependencies to ensure a thorough cleanup. For instance, a mechanical engineer upgrading from SolidWorks 2020 to 2023 might encounter lingering components that interfere with new installations or system performance. This process is critical for reclaiming storage, resolving conflicts, and preparing systems for alternative CAD software or operating system updates.

The importance of proper removal stems from SolidWorks' deep integration with Windows, including custom DLLs, registry keys, and service dependencies. Leaving remnants behind can cause crashes, licensing errors, or slower system responses. Historically, early versions of SolidWorks relied on manual cleanup tools, but modern iterations demand systematic approaches to avoid fragmentation. Whether transitioning to Fusion 360, troubleshooting a failed update, or simply freeing up space, a meticulous removal process is essential.

This guide covers every aspect of removing SolidWorks, from standard uninstallation steps to advanced troubleshooting for stubborn files. It includes tools, verification methods, and best practices to ensure a clean slate, whether the goal is to switch software, resolve errors, or optimize system performance.

1. Standard Uninstallation Steps

Begin with the official uninstaller provided by SolidWorks. Navigate to the Control Panel on Windows, locate 'Programs and Features,' and select 'SolidWorks [Version].' Click 'Uninstall' and follow the prompts, which may include removing user preferences or product data. This method removes the main application but often leaves behind support files, templates, and registry entries.

For macOS users, SolidWorks can be uninstalled via the Applications folder by dragging the SolidWorks icon to the Trash. However, macOS retains cache and preference files in the Library folder, requiring manual deletion. Always back up critical project files before proceeding, as these steps do not recover deleted data.

2. Manual File Cleanup

After uninstalling, residual files can accumulate in several locations. Use the following checklist to identify and remove them:

• Program Files and ProgramData: Delete folders like `C:\Program Files\SolidWorks [Version]` and `C:\ProgramData\SolidWorks`. These contain executables, DLLs, and configuration files. For example, `C:\Program Files\SOLIDWORKS Corp\SOLIDWORKS [Version]` holds core application files that must be removed to free up gigabytes of space.
• User Profile Directories: Check `%AppData%\SOLIDWORKS` and `%LocalAppData%\SOLIDWORKS` for user-specific settings, toolbox data, and macros. These folders store customizations that may not be needed after removal, but back up any critical macros before deletion.
• Windows Registry: Use the built-in Registry Editor (`regedit`) to navigate to `HKEY_LOCAL_MACHINE\SOFTWARE\SolidWorks` and `HKEY_CURRENT_USER\Software\SolidWorks`. Delete these keys to remove software references, though caution is advised—incorrect edits can destabilize the system.
• Shortcuts and Desktop Icons: Delete any remaining desktop shortcuts or Start Menu entries. These are harmless but contribute to visual clutter and may inadvertently launch residual processes.
• Recycle Bin: Empty the Recycle Bin after deleting files to ensure permanent removal. Some uninstallers skip this step, leaving temporary files that can be recovered.

3. Using SolidWorks Cleanup Utilities

SolidWorks provides official cleanup tools to automate the removal of leftover files. The SolidWorks Installation Manager includes a 'Repair/Remove' option that scans for and removes residual components. Download the latest version from the SolidWorks website to ensure compatibility with the installed version.

Third-party tools like Revo Uninstaller or Geek Uninstaller offer deeper scans and can detect hidden files missed by standard uninstallers. These tools analyze system changes during uninstallation and prompt for removal of leftover entries. For example, Revo Uninstaller’s 'Hunter' mode identifies orphaned DLLs linked to SolidWorks that might cause future conflicts.

4. Registry Editor Deep Clean

The Windows Registry stores critical configuration data, and SolidWorks leaves entries under keys like `HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\SolidWorks` and `HKEY_CURRENT_USER\Software\SOLIDWORKS`. To clean these:

• Backup the Registry: Before making changes, export the entire registry or specific keys to a `.reg` file. This step is non-negotiable—registry corruption can render a system unusable.
• Locate SolidWorks Keys: Use the 'Find' function in Registry Editor (`Ctrl+F`) to search for terms like `SOLIDWORKS`, `SW`, or `DS`. Delete any matching keys, including subkeys under `HKEY_CLASSES_ROOT` that may reference SolidWorks file types.
• Verify System Stability: After deletion, restart the computer and monitor for errors. If the system fails to boot, restore the registry from the backup and attempt a more selective cleanup.
• Use a Registry Cleaner: Tools like CCleaner or Auslogics Registry Cleaner can automate this process, but manual verification is recommended to avoid overzealous deletions.

5. Troubleshooting Stubborn Files

Some files remain locked due to active processes or permissions. To resolve this:

Use Process Explorer from Microsoft’s Sysinternals suite to identify processes holding files open. Right-click the file in File Explorer, select 'Open with...', and choose Process Explorer to reveal the locking process. End the process via Task Manager, then delete the file. For example, `sw.exe` or `swcc.exe` might retain handles on temporary files during shutdown.

Administrative permissions are required for some deletions. Right-click File Explorer, select 'Run as administrator,' and attempt deletion again. If the file is still inaccessible, boot into Safe Mode to bypass background services that might be locking resources.

6. Verifying Complete Removal

After cleanup, verify that SolidWorks is fully removed by checking for:

• No Running Processes: Open Task Manager and confirm no `sw*` processes are active. Use the 'Details' tab to filter for SolidWorks-related entries.
• Missing File Associations: Attempt to open a `.sldprt` or `.sldasm` file. If no application launches, SolidWorks is successfully removed. Reassociate file types if needed using Windows Settings.
• Clean Registry: Reopen Registry Editor and search for `SolidWorks`. No entries should remain under `HKEY_LOCAL_MACHINE` or `HKEY_CURRENT_USER`.
• Disk Space Recovery: Compare free disk space before and after removal. A successful cleanup typically recovers 1–3 GB, depending on the version and customizations.
• No Start Menu Entries: Search the Start Menu for 'SolidWorks.' If no results appear, the uninstallation is complete.

7. Reinstalling SolidWorks After Removal

If reinstalling SolidWorks post-removal, ensure all residual files are deleted to avoid conflicts. The installer may detect old versions and prompt for repair, which can fail if dependencies are missing. Always download the latest installer from the SolidWorks website and use the 'Custom Install' option to specify installation directories.

Licensing issues may arise if the original license server is still referenced in the registry. Use the SolidWorks License Manager to clear old licenses and register new ones. For network deployments, coordinate with IT to ensure license servers are updated to reflect the removal.

8. Alternative Software Considerations

Removing SolidWorks often precedes a switch to alternative CAD tools like Fusion 360, AutoCAD, or FreeCAD. Each platform has distinct installation requirements and may conflict with leftover SolidWorks components. For example, Fusion 360 integrates with Autodesk’s ecosystem, so residual SolidWorks plugins could disrupt workflows.

Evaluate compatibility before switching. Some alternatives, like Onshape, operate entirely in the cloud and require no local installation, making them ideal for users seeking to avoid legacy software conflicts. Always test the new software on a clean system to identify potential issues early.

Frequently Asked Questions

Removing SolidWorks can raise specific questions about the process, tools, and potential pitfalls. Here are six common inquiries:

Question 1: Can I remove SolidWorks without affecting my projects?

Yes, but back up projects first. SolidWorks stores project files separately (e.g., `.sldprt`, `.sldasm`), which remain intact during removal. Only user-specific settings, toolboxes, and macros in `%AppData%` are deleted unless explicitly saved.

Question 2: Why does SolidWorks keep reinstalling itself?

This typically occurs due to corrupted registry entries or a partial uninstall. Use the SolidWorks Installation Manager to force-remove the application, then scan the registry for leftover keys. Third-party uninstallers can also detect and purge residual components.

Question 3: Are there risks to manually editing the registry?

Yes, incorrect edits can cause system instability or crashes. Always back up the registry before making changes. If unsure, use a registry cleaner tool or consult SolidWorks support for guidance on safe key removal.

Question 4: How do I remove SolidWorks from a domain-managed computer?

Domain policies may restrict uninstallation. Contact IT to temporarily disable restrictions or use a deployment tool like Microsoft Endpoint Configuration Manager. Ensure the license server is updated post-removal to avoid conflicts with other users.

Question 5: Can I use third-party uninstallers for SolidWorks?

Yes, tools like Revo Uninstaller or IObit Uninstaller can detect and remove leftover files more thoroughly than the standard uninstaller. However, verify the tool’s compatibility with SolidWorks to avoid false positives or aggressive deletions.

Question 6: What should I do if SolidWorks won’t uninstall?

Boot into Safe Mode to bypass background services, then use the Installation Manager or a third-party tool. If the issue persists, contact SolidWorks Support with logs from the uninstallation process for targeted assistance.

9 Tips for a Flawless Removal

Ensuring a complete and error-free removal of SolidWorks requires precision. Follow these nine actionable tips to streamline the process:

Tip 1: Document your SolidWorks version. Note the exact version (e.g., 2023 SP5) to download the correct cleanup tools or registry keys. Mismatched versions may leave remnants or cause installation conflicts.

Tip 2: Disable antivirus temporarily. Security software may block file deletions during cleanup. Pause real-time protection for the duration of the removal to avoid interruptions.

Tip 3: Use the Installation Manager first. Always run the official SolidWorks Installation Manager before manual steps. It handles most dependencies and reduces the risk of system errors.

Tip 4: Check for pending updates. Windows Update may install SolidWorks-related patches post-removal. Use the 'View Update History' tool to identify and manually uninstall any SolidWorks updates.

Tip 5: Verify file permissions. Right-click folders like `Program Files\SolidWorks` and select 'Properties > Security' to ensure your user account has full control. Restricted permissions can prevent deletions.

Tip 6: Test in a virtual machine first. If unsure about manual registry edits, replicate the process in a VM to observe system behavior without risking your primary machine.

Tip 7: Clean up network locations. SolidWorks may store files on shared drives (e.g., `\Server\SW_Data`). Delete any folders named after your user profile or project templates.

Tip 8: Monitor disk space post-removal. Use Windows’ 'Storage Settings' to confirm space recovery. Discrepancies may indicate missed files or hidden partitions.

Tip 9: Reinstall only after full verification. Wait 24 hours before reinstalling to ensure no residual processes are active. This reduces the chance of conflicts during the new installation.
