Updating cursor, deletes it and then i have to redownload

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

So last few months, every single time I try to update. It removes cursor, gives an error asking to double check if any cursor processes that are still runinng (which there aren’t). Then I click cancel and cursor is gone and i have to re-download from the site again.

I added the last error I got.

Steps to Reproduce

Every single update, when i press update.

Expected Behavior

Well it should just update the version.

Screenshots / Screen Recordings

Operating System

Windows 10/11

Version Information

Can’t really provide, seeing as it’s gone. But it’s been the last several updates.

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey there! That first dialog is the key one, and clicking Cancel is what leaves you with nothing to launch (some old files are already gone by then). The delete fails because a leftover Cursor helper process, usually a node.exe from an MCP server or extension (sometimes rg.exe), is still holding files in the install folder.

Next time it shows up: open Task Manager, end any lingering Cursor / node.exe / rg.exe processes, then click Retry (not Cancel).

To reduce how often it happens:

  1. Add your install folder (C:\Users\<you>\AppData\Local\Programs\cursor) as an antivirus/endpoint-security exclusion.
  2. In settings.json, set "update.enableWindowsBackgroundUpdates": false so updates apply on restart instead of while Cursor is running.

Neither is a full guarantee, and what you’re seeing isn’t intended behavior, it’s not something you misconfigured. Our team is looking into this. Longer-running thread to follow along here.
