Cursor IDE

Describe the Bug

When attempting to update cursor on windows, I get an error that reads that there was an error opening the file handle “the process cannot access the file because it is in use by another process.”

I’ve tried restarting and shutting down any cursor.exe process in my task manager. Can’t seem to get it to work. Is there another fix?

Steps to Reproduce

Open the Cursor IDE

Update with the prompt in the lower left

Error appears

  • or -

Use the help menu to check for update

Restart cursor

Error appears

Expected Behavior

Cursor updates successfully without failing

Additional Information

I can still use cursor except on a larger product I’m building, the agent keeps failing to update context. In the past updates typically solved this. I’ve lost a few days of work because of this. I love cursor so nbd in the grand scheme of things, I would like this fixed sooner than later tho.

hi @Sardius can it be that the cursor file is being locked by some other process like an antivirus or an still open Cursor instance?
