Hi Sergio###,
Thank you for reaching out to Microsoft Community.
May I know if you get an error message when you tried to run CATIA on your Surface Book 2? If yes, please share the error message with us. If none, please let me know what happens every time you try to launch the app.
For now, please do these steps to troubleshoot the issue:
1: Run Surface Diagnostic Toolkit and check Windows Update
2: Update drivers and firmware
Check what is the current OS Build of your Windows version by going to Settings > System > About.
Go to Download driver and firmware for Surface, choose Surface Book 2 then click Download on the next page.
Choose the .msi file that matches your current OS Build and click Next.
After downloading, run and install the .msi then Restart.
3: Run System File Checker Tool in Windows 10
If this answer your question, we highly encourage you to inform our Community by clicking on Yes or marking my post as an answer. This will help other members who may have the same issue as you. Otherwise, don't hesitate to update us so we can further assist you.
