If you’re seeing the frustrating ‘Session expired’ message in 3DEXPERIENCE SOLIDWORKS, you’re not alone. This 3DEXPERIENCE SOLIDWORKS session expired issue can disrupt your workflow, but don’t worry—there’s a quick fix. In this guide, I’ll share two easy solutions to help you resolve the problem and get back to work without delay.

Solution 1: Reinstall the 3DEXPERIENCE Launcher

First, let’s address potential issues with the 3DEXPERIENCE Launcher itself. To begin with, follow these steps:

Uninstall the 3DEXPERIENCE Launcher

Navigate to your system’s application manager.
Locate the 3DEXPERIENCE Launcher and uninstall it completely.

Reinstallation of the Launcher

- Download the latest version of the 3DEXPERIENCE Launcher from the Compass .
- Follow the installation instructions to set it up again.

Launching SOLIDWORKS Connected

- Open the Compass and click on “SOLIDWORKS Connected” application .
- Following these steps should resolve the issue and allow you to proceed without encountering the error message.

Solution 2: Launch a Different App to Refresh Your Session

Another option is to refresh your session by launching a different app within the 3DEXPERIENCE Platform. Here’s how you can do it:

Access a Different Application
- Click on an app like 3DDashboard, 3DSwym, or any other application that opens in a new browser tab.

Why These Solutions Work

Reinstalling the Launcher ensures that any corrupted files or outdated components causing the issue are replaced with a fresh version. On the other hand, refreshing the session through a different app establishes a new authentication flow, which allows SOLIDWORKS Connected to launch successfully. Hopefully, this 3DEXPERIENCE SOLIDWORKS session expired fix will help you get back to work smoothly.

Technical glitches can be an inevitable part of using advanced platforms like 3DEXPERIENCE. Nevertheless, knowing how to troubleshoot effectively can save you time and frustration. Hopefully, these solutions will help other users who face the same issue. If you have further questions or additional tips, feel free to share them in the comments or contact support for assistance.

Ultimately, I hope SOLIDWORKS and 3DEXPERIENCE address this bug in future updates, providing a seamless user experience.

Thank you for reading!
