Spotify Error Code 18 — What It Means & How to Fix It

What it means

Spotify Error Code 18 means the Spotify installer could not complete the installation or update.
This usually happens because a previous Spotify process is still running in the background, blocking the installer.
Closing all Spotify processes and retrying the installation fixes this in most cases.

Affected Models

Spotify on Windows 10
Spotify on Windows 11

Common Causes

A Spotify process is still running in the background, preventing the installer from replacing its files
Leftover Spotify files from a previous installation are conflicting with the new install
You do not have administrator rights on the computer and cannot complete the installation
Antivirus software is blocking the Spotify installer from writing files to your computer
The Spotify installer file itself was downloaded incompletely or became corrupted

How to Fix It

Open Task Manager (Ctrl+Shift+Esc) and look for any Spotify processes in the list. Right-click each one and choose 'End Task'.

Spotify sometimes runs multiple background processes.
Make sure every Spotify-related entry is closed before proceeding.
Restart your computer, then immediately try running the Spotify installer again before opening any other programs.

Restarting clears all background processes, giving the installer a clean environment.
Uninstall Spotify completely through Control Panel > Programs > Uninstall a program. Then delete leftover Spotify folders in %appdata% and %localappdata%.

Press Windows+R and type %appdata% to navigate there.
Delete any Spotify folders you find in both locations.
Download a fresh Spotify installer from spotify.com/download. Right-click the installer and choose 'Run as administrator'.

Always download a fresh installer — do not reuse the old file.
If the error still appears, temporarily disable your antivirus and retry. Re-enable it immediately after Spotify installs.

Some antivirus programs block Spotify's installer even though Spotify is safe software.

When to Call a Professional

Error Code 18 is a local installation problem that you can fix yourself.
If Spotify repeatedly fails to install even after a clean removal, contact Spotify Support with the installer log file.
The log file is typically found in %temp%\Spotify_installer.log

Frequently Asked Questions

Does Error Code 18 mean my Spotify account has a problem?

No.
Error Code 18 is purely an installation issue on your computer — it has nothing to do with your account.
Your account, playlists, and subscriptions are completely unaffected.
Once Spotify installs successfully, your account will work exactly as before.

Can I install Spotify without administrator rights?

Yes — Spotify is designed to install per-user without requiring admin rights.
However, if you previously installed Spotify system-wide (for all users), removing that version may require admin rights.
If you are on a work or school computer, ask your IT administrator for help.

Where can I find Spotify's installer log to share with support?

Press Windows+R, type %temp%, and press Enter.
Look for a file called Spotify_installer.log or similar.
This file contains detailed information about why the installation failed.
Attach it when contacting Spotify Support for faster diagnosis.
