Hi SorayaConde,
Thank you for reaching Microsoft Community. We appreciate for sharing your concern to us. Let me ask few questions to help us further isolate the issue.
Which Surface pro device do you have, the Intel or 5G (SQ3) Arm device?
What error message did you get when trying to install the app?
What build version of Windows 11 are you on?
Are you referring to Microsoft Journal app and Good Notes app for Windows?
For the meantime, you may run the step below.
Check Windows Updates
Go to Settings >> Windows updates >> Check for updates. Also check optional updates if available and install them.
Most common issues can be solved by running the Surface Diagnostic Tool. ****
I look forward to hearing from you.
Kind regards,
Lavenia
