Cursor IDE
This still happens, even on cursor 3+
Had it happen today again.
How should I know
Windows 10/11
Cursor is gone, nothing to check. Last installer I downloaded was CursorUserSetup-x64-3.0.12.exe
Sometimes - I can sometimes use Cursor
Hey, thanks for the repeat report. This is a known issue with the Windows auto-updater. If the system restarts or something interrupts the update process between uninstalling the old version and installing the new one, Cursor can disappear completely.
The fix in v2.5.26 covered some cases, but clearly not all of them. The team is aware it still reproduces on 3.0.x. Your report helps raise the priority.
For now, a workaround:
Let me know if you notice any specific pattern, like whether it only happens after an update or sometimes after a normal restart too.
It’s gone again today, after making sure it was fully shut down before turning off my PC.
I start Cursor from within WSL if that helps.
Me too, 2nd time in a week! I noticed a new version was available yesterday and I clicked “later”… but after this morning’s boot the whole thing has gone, haha
What still happens even after a full close is useful info, so it’s not just about the process getting interrupted on shutdown.
The WSL detail could be important. A couple of questions:
cursor . in a WSL terminal?As a temporary workaround, you can try turning off auto-updates: File > Preferences > Settings, search for update.mode, and set it to none. You’ll need to install updates manually, but at least Cursor shouldn’t disappear.
The team is aware of this bug. Your report helps with prioritization, especially the WSL detail.
I mostly boot cursor via cursor . in WSL. Sometimes straight from Windows for projects that are not tied to WSL.
I run Ubuntu 22 and 24 on two different devices, both have the issue.
@tiz.io, thanks for another report. The auto-uninstall bug on Windows is already being tracked, and your report helps with prioritization.
About SmartScreen, the installer is actually signed by Anysphere, Inc. You can see that in the Publisher field on your screenshot. This isn’t an expired or missing certificate. It’s a reputation-based warning that Microsoft shows for newer binaries until they build enough reputation. Click More info → Run anyway and the install should work fine.
There’s a parallel thread on the same topic with a bit more detail: No auto update & Windows installer not recognized by windows?
We don’t have an ETA for the auto-uninstall fix yet. If you notice any pattern, like only after an update vs after a normal reboot too, or whether Cursor was launched via WSL, please share it in the thread. It really helps narrow down the cause.

Whenever I update my cursor, it throws the error . Also, while updating, I think it is deleting the earlier Cursor install app, and I need to download and install Cursor again
Click on the update button, which displays whenever there is a new update, and wait for some time
Cursor needs to be updated and it needs to reopen automatically
Windows 10/11
As my previous cursor was uninstalled during the update process, I am not able to find it
Yes - Cursor is unusable
I faced this issue while upgrading to Version 3.2.10 today. i had to reinstall and everything works fine now. oh that was a surprise when cursor got completely uninstalled!
It happened again for me today. I’m switching to manual update only for now.
Hi folks! Sorry to hear about this issue. When someone runs into this problem, can you confirm whether the steps below work?
Open Start
Search Windows Security and open it
Go to Virus & threat protection
Click Protection history
Find the detected/quarantined item in the list
Click it to expand details
From there you can:
See the file name and original path
Restore it (if you trust it)
Remove it permanently
It’s possible that Windows Defender is silently quarantining our new binary and would be great to confirm!
I’m using Sentinel Agent. There is nothing Cursor-related listed in the Threat or Quarantine history.
Like another user here, I specifically clicked “Later” on the update notice but Cursor got uninstalled anyway when I rebooted my PC. I have turned off auto-updates for now.
Got it! This might be a known inconsistent issue we inherited from VSCode ( Visual Studio Code Completely Uninstalls Itself on Update · Issue #147322 · microsoft/vscode · GitHub ).
Are you using the user installer? Could you swap to the system installer and see if you still run into this?
Cursor IDE
Cursor gets uninstalled every time I close it! Why?! Windows 10, latest Cursor version.
Close Cursor
Some errors on Windows 10
Try to Open cursor again
Not there anymore
Windows 10/11
No idea, latest version, it already got uninstalled.
Yes - Cursor is unusable
just happened to me also
@happypopcorn @Liam_James thanks for the reports. We’re tracking the issue, but there’s no ETA yet.
@happypopcorn, “it disappears every time after closing” sounds like a stronger pattern than what others in the thread describe. A few quick questions so we can add more detail to the issue:
%LOCALAPPDATA%\Programs\cursor\ user installer or C:\Program Files\cursor\ system-wide? If you have both at the same time, it might be related to this dual install bug: Windows updater fails with dual install (system-wide + per-user) and leaks ~2GB of temp folderscursor ., or directly from Windows?Workaround for now: turn off auto-updates. Go to File > Preferences > Settings, search for update.mode, and set it to none. You’ll need to update manually, but it should stop disappearing.
@Liam_James, if you can, please share the same details too: version, install type, WSL or not, and antivirus. It helps narrow down the cause.
Steps to reproduce:
Get Cursor update notification. press shut down Windows system without closing cursor before that.
Have the same issue here, for the last 2 versions.
While working with cursor, an update popup appears asking me if I want to install. I simply press Install and it starts to throw errors. And no cursor processes still running!
Just a note: While doing this cursor was running 3 wrangler executables in the background for my localhost tests. After installer runs, they also got destroyed as I can see but didn’t dig much in details.
And I couldn’t install cursor again without restarting the PC.
Another note: PC was freshly restarted before clicking “Install” (couple of hours ago without any updates, etc done before).

this is 3rd time happening in 2 days with 3 different cursor versions!
