Fix Notepad++ When It Won't Update
Notepad++ stuck on an old version? Close the app fully, allow gup.exe through the firewall, run it as admin, or reinstall over the top to fix it.
Notepad++ usually updates itself, so when it refuses, start simple: close every window, reopen it, and run ? > Update Notepad++. The built-in updater cannot replace files while the editor is open, so a running instance is the most common reason the check does nothing. If it still fails, the cause is usually the safety delay, a blocked connection, or missing write permission, and a reinstall over the top clears all three.
Check the “safety delay” first
Notepad++ deliberately holds back auto-update for one to two weeks after a release, so a buggy build never reaches everyone at once. That means “No new version found” can be correct even when the downloads page lists a higher number. The delay affects only the automatic check, never a manual download. Review or turn it off under Settings > Preferences > MISC.
Let the updater actually run
The updater is a separate tool called WinGUp (gup.exe, in the updater folder of your install). It exists only if you used the installer and kept the auto-updater option; the portable zip has none. Close Notepad++ fully before updating; on the portable build, download the new zip.
Match the symptom to the fix
| Symptom | Likely cause | Fix |
|---|---|---|
| Click Update, nothing happens | Still open, maybe in the tray | Close every window, then retry |
| Up to date on an old build | Safety delay, or updater set to off | Check Settings > Preferences > MISC; install manually |
| Updater opens, then fails quietly | gup.exe blocked by firewall or proxy | Allow gup.exe outbound in your security software |
| Download runs but install fails | No admin rights in Program Files | Run Notepad++ or the installer as administrator |
When in doubt, reinstall over the top
The reliable fix skips the updater: download the current installer from the official Notepad++ site, pick the 32- or 64-bit build, and run it. Installing over an existing copy keeps your settings and sessions intact. It is the same clean-slate move that clears a driver that refuses to install or Excel that stops responding.
If the download stalls, low disk space is often the culprit; freeing up space on Windows 11 gives the installer the room it needs. Keep the installer afterward, since running it again is the quickest fix next time the check stalls.
