Hey, this is a known issue that’s been reported by multiple users, especially on Windows. There are usually two main causes:
-
Windows auto-updater bug
Cursor’s Electron auto-update can sometimes fail in a way that removes the existing install without finishing the new one. A fix was shipped related thread, but some users still hit it. -
Corporate antivirus or security policies
Since you mentioned needing IT approval, this is likely involved. Many corporate security tools (Windows Defender via GPO, CrowdStrike, Zscaler, etc.) will quarantine or remove apps that aren’t on the approved software list. That would explain why it keeps disappearing.
A few things to check:
- Ask your IT team to check the antivirus or endpoint protection quarantine logs for any Cursor entries
- Have IT whitelist the Cursor install folder (usually
%LocalAppData%\Programs\Cursor) - If it seems update-related, try running these PowerShell commands as admin to rule out system file corruption:
SFC /scannow DISM /Online /Cleanup-Image /RestoreHealth
Can you share your Windows version and which antivirus or endpoint protection your company uses? That’ll help narrow it down.
