Issue Description

I'm experiencing consistent problems when trying to update Heynote using the built-in update feature. When a new version is available and I click the update button, the software automatically downloads the new installation file and launches the installer. However, the installation process fails midway with an error message suggesting that the application is still running, which prevents the update from completing.

Current Behavior

1. New version notification appears in the application
2. I click the update button
3. The new version is downloaded and the installer launches automatically
4. Midway through installation, an error appears indicating that the application is currently running (something similar to "application is in use" or "cannot update while application is running")
5. If I cancel the update, the previous version appears to be uninstalled, leaving me with no working version

Expected Behavior

The update process should either:

• Automatically close the running instance before attempting to install the new version
• Prompt the user to close the application before proceeding with the update
• Complete the update successfully without requiring manual intervention
• Workaround
• Currently, I have to manually download the latest installation file from the official website and perform a manual installation to update the software. The built-in update functionality is essentially unusable.

Additional Information

• This issue occurs consistently with every update attempt
• Operating System: Windows11
• I would appreciate any assistance in resolving this issue so that I can use the built-in update feature as intended.
