Quick Summary
Discord Error 1105 generally indicates a problem during the application's update process. This usually stems from issues with file permissions, corrupted installation files, or conflicts with other software.
Common Causes
- Insufficient Permissions: Discord might not have the necessary permissions to modify its installation files, preventing the update process from completing successfully.
- Corrupted Installation Files: The existing Discord installation may be corrupted, leading to errors when the updater attempts to modify or replace those files.
