Hey, thanks for the report. This is a known issue on Windows. Usually Windows Defender or another antivirus quarantines Cursor files, especially when you’re using the user setup version.
Try this:
- Check Windows Security → Virus & threat protection → Protection history. Cursor might be quarantined there.
- Add the Cursor folder to your antivirus exclusions, usually
C:\Users\[username]\AppData\Local\Programs\cursor. - Reinstall using the system installer from Download · Cursor. It installs into Program Files instead of AppData, which reduces the chance of antivirus false positives.
Also check if any disk cleanup tools are running. Some aggressive cleaners can remove apps from your user profile.
The system installer usually fixes this completely because it installs with system permissions.
