Hey, thanks for the report. Please try running the installer as administrator (right‑click → “Run as administrator”). If that doesn’t help, follow these steps:

  1. Kill any CursorSetup processes in Task Manager
  2. Clear your temp folder (%temp%) of any Cursor‑related files
  3. Download a fresh installer from https://cursor.com
  4. Temporarily disable Windows Defender/antivirus during installation

Let me know if running as admin helps, that usually fixes most installer hangs on Windows 11.

Once I disabled the antivirus software, I was able to install. Thanks!
