I installed an extension, I was told to reload Cursor to start using it. I closed Cursor IDE and tried to reopen it, Windows told me that this is no longer installed. So I had to reinstall Cursor again. Perhaps this isn’t directly related to installing an extension, but that’s when I noticed the behavior.
Steps to Reproduce
Install an extension (in this case, it was DBCode)
Attempt to restart Cursor
Expected Behavior
Cursor should not be uninstalled after installing an extension
Hi @Cameron_Vigil Thanks for your forum post! Your install is fine, and it turns out you didn’t actually need to reinstall. Here’s what I think happened. An update to 3.15.6 finished downloading and became ready at almost exactly the moment DBCode asked you to reload. The restart you triggered applied that update rather than just reloading the window. While an update is being applied on Windows, Cursor is replaced on disk and is unavailable for a short stretch, around 40 seconds in your case. If you launch the shortcut during that window, Windows reports that the application is no longer installed, which is the message you ran into. Once the update finished, Cursor came back on its own as 3.15.6 with the installation intact.
So nothing was lost or damaged, and the extension didn’t break anything. Installing DBCode just happened to prompt a restart at the same moment an update was ready to apply.
If you hit this again, give it a minute after a restart before relaunching and Cursor should come back by itself. Re-running the installer does no harm, it just wasn’t necessary here. Let me know any follow-up questions!
