Why does my cursor 0.45.5 version automatically uninstall itself?

Why does my cursor 0.45.5 version automatically uninstall itself? I have reinstalled it several times, but it still automatically uninstalls itself after closing the window. My operating system version is Windows 11

Hey, one possible reason is that Cursor is attempting to update, but for some reason, it can’t retrieve the update. It deletes the old version to install the new one, but since the new version isn’t available, there’s nothing to install.

yeah then how about it uninstalls the old version AFTER installing the new version, or at least keeps the old version as a backup to fallback onto when something fails? come on guys, it’s an IDE you charge money for, not a hobby project.

This is probably the 5-6th instance this is happening. And its not an unknown issue…

Same issue - with 2 different computers. Fresh install current downloadable version, after install tries to update and completely disappears.

The only way to get it back is to relaunch the original installer, and midway through the installation Cursor comes back. Without icon by the way - its in a limbo status, but at least it works

Same issue on Windows 11. It’s super annoying to have to randomly re-install every few days if not multiple times per day. This has been ongoing for the past 3-4 months.

Same exact issue. Multiple times a day.

For what it’s worth, I know this is going to happen during reboots because when I shut down Windows asks me whether I’m sure I want to shut down. The reason it’s asking is because the Cursor installer is apparently still running— which it should not be given that it’s already installed and I’ve been using it all day.

Same thing just started happening to me as well. This is very annoying and makes Cursor almost unusable.

This is happening to me as well even with the latest version, but only when I execute a git operation from the terminal. For example, if I type

git commit --amend

and finish amending the commit (opened as a buffer within cursor), it crashes and seemingly uninstalls. Another operation is

git rebase -i branch

Which opens the interactive rebase git dialog (in cursor), and crashes and uninstalls after I finish picking the commits.

Has anyone else experienced this?

Windows Troubleshooting Instructions

If you’re experiencing this issue on Windows, follow these steps. In my case, the problem wasn’t directly tied to Cursor - likely system files on your system causing the issue. These steps will clean up your system and resolve underlying problems.

1. Uninstall and Reinstall Cursor

  • Uninstall Cursor (if installed):

    • Open Settings and go to Apps & Features (or use Add or Remove Programs in the Control Panel).
    • Locate Cursor in the list and uninstall it if it’s still installed.
  • Download the Latest Version:

    • Visit the official Cursor website to download the latest version.
    • Install the new version after the download is complete.

2. Run System Cleanup Commands in PowerShell

  1. Open PowerShell as Administrator:

    • Click the Start button, type PowerShell, right-click on it, and select Run as Administrator.
  2. Run the Following Commands One at a Time:
    Copy and paste each command into PowerShell, pressing Enter after each to ensure it completes before proceeding to the next.

    DISM /Online /Cleanup-Image /StartComponentCleanup
    DISM /Online /Cleanup-Image /CheckHealth
    DISM /Online /Cleanup-Image /ScanHealth
    DISM /Online /Cleanup-Image /RestoreHealth
    SFC /scannow
    

*Note: SFC /scannow is what fixed it for me, but the other commands are good to run in this instance if you’re having this issue.

3. Check Your Hard Drive for Errors

As a bonus step, check your hard drive for issues. This process takes time, so consider running it before a long break.

  • Run CHKDSK:
    Open PowerShell as Administrator (if not already open) and run:

    CHKDSK C: /F /V /R /offlinescanandfix
    
  • Reboot Your Computer:
    Once CHKDSK is complete, restart your computer to apply any changes.


Hope this helps!

So you are telling me that, the hundreds of people reporting the same issue on Github within a week - and myself just have bugged windows, and its not Cursor related?

Though VSC etc remains stable, but its just cursor for everyone?

I’m not telling you anything. I don’t work for Cursor. I’m just suggesting a fix that worked for me. When I was having the issue, I noticed it was something that happened with VSCode too. Google it. Its certainly possible a previous Cursor install caused a corrupt Windows installer. I don’t know or care to track down the root cause. All I know is running “SFC /scannow” resolved it for me and I haven’t had the issue since. It literally takes like a minute to run it, five to go through the clean steps I suggested. No harm, no foul. Happy coding!

thanks for the clarification and the detailed troubleshoot MR D, im gonna give that a whirl :wink:

So the issue is related to it uninstalling it self before installing it’s update. You’ll see that the AppData is missing, but navigating to %AppData%..\Local\cursor-update\ and check for pending if you have an update. INSTALL THE UPDATE FROM HERE Do not keep downloading the version from their website as it’s not the “current” version so you end up in the same loop. I’m not sure as I haven’t put a trace on it, but I think when there’s a pending update and you close (shutdown which I often go straight to shutdown) with a pending update, cursor tries to install it, removes the old (current) version and then times out, (in my case I’m shutting down the PC) so the update doesn’t get a chance to install. This way you are “manually” installing the current updated version. This is obviously a bug they need to fix but hopefully this gives you a work around as the version on the site is old and just keeps you in this never fully updated loop!

In there I have a JSON file showing an updated version

{"fileName":"Cursor Setup 0.45.10 - Build 250205buadkzpea.exe","sha512":"Y4swAp6UV3njSOf0bKJLX1yHy4UDYwb0zYNRlnZBXlz0u2lz0f1sESWf0F7LHBI5CgBlqnZ40CxWCS8mOq98FQ==","isAdminRightsRequired":false}

It also helps if you add both %APPDATA%\Local\Cursor and cursor-update to your A\V Exclusions, navigate to Windows → Settings → Security → Virus & Threat Protection → Manage Settings → Exclusions → Add both
%AppData%\Roaming\Cursor
%APPDATA%\Local\Programs\cursor
%APPDATA%\Local\cursor-update

Good Luck~ Bizanator


Aparently I can’t add more than 1 image at a time so here’s the path and the update file, INSTALL THIS ONE and you should be good (at least till the next update lol)

AppData\Local\cursor-updater\pending
