Once the installer file is downloaded, it’s time to install CCleaner. Here’s how:

Locate the Installer File
Find the CCleaner installer file in your downloads folder (or the folder you’ve designated for downloads). The file will typically be named something like ccsetup.exe.
Run the Installer
Double-click the installer file to begin the installation process. If prompted by your system's security warning, click Run or Yes to allow the program to make changes to your system.
Choose Installation Options
The CCleaner installation wizard will guide you through the process. You’ll be asked to choose various installation options:
- Standard Installation: Recommended for most users. This will install CCleaner with default settings.
- Custom Installation: If you prefer, you can select this option to specify where CCleaner will be installed and whether or not to install additional tools such as browser plugins.
Agree to the Terms and Conditions
You’ll need to accept the software’s terms and conditions before continuing with the installation. Review the license agreement, and then click Accept to proceed.
Begin Installation
Click the Install button, and the installation process will begin. The process usually only takes a few minutes.
Finish Installation
Once the installation is complete, you’ll see a confirmation screen. You can now click Finish to exit the installer and launch CCleaner.

Before you get started, make sure you download the setup file here.

Step 3: Activating CCleaner Pro (if Applicable)

If you’ve purchased CCleaner Professional, you’ll need to activate it using your license key. Here’s how to do that:

Launch CCleaner
After installation, CCleaner should automatically open. If it doesn't, you can launch it from your desktop or start menu.
Enter Your License Key
- Click on the Options button in the left panel.
- Navigate to the About section.
- In this section, you’ll find an option to enter your License Key.
- Copy and paste your license key from the email you received after purchasing CCleaner Pro.
Activate Your License
After entering the key, click Activate. The software will validate the key and, if correct, will upgrade your CCleaner to the Pro version. You'll now have access to all premium features.
Confirm the Activation
Once activated, you should see a confirmation message. Your CCleaner software is now fully licensed, and you can start using it to optimize your system.

Step 4: Setting Up CCleaner for Automatic Cleaning (Optional)

One of the key advantages of CCleaner Pro is its ability to schedule regular cleaning sessions automatically. Here’s how to set it up:

Open CCleaner and Navigate to the "Options" Tab
On the left sidebar, click Options, then select Settings.
Enable Automatic Cleaning
Under the Cleaning Schedule section, check the box that says Enable Automatic Cleaning. You can customize the frequency (daily, weekly, or monthly) and set a time for the cleanup.
Save Your Settings
Once you've customized your cleaning schedule, make sure to click Save. CCleaner will now automatically clean your system according to the schedule you've set.

Step 5: Running Your First System Cleanup

Now that CCleaner is installed and activated, it’s a good idea to run a full system cleanup to optimize your computer.

Step 6: Keeping Your CCleaner Up to Date

To ensure you have the latest features and security updates, it’s important to keep CCleaner up to date:

Check for Updates Manually
CCleaner will typically notify you when an update is available. However, you can also check manually by clicking on the Options menu and selecting Check for Updates.
Enable Auto Updates (Optional)
You can enable automatic updates so CCleaner updates itself when new versions are released. This option can be found under the Settings section in the Options tab.

Troubleshooting Common Installation Issues

While installing CCleaner is generally straightforward, you might encounter a few issues. Here are some common troubleshooting steps:

Installer Won’t Launch
If the installer doesn’t open, try running it as an administrator (right-click the installer file and select Run as Administrator). If that doesn't work, temporarily disable any antivirus software that might be blocking the installation.
License Key Not Working
Double-check that you’re entering the correct license key. Make sure there are no extra spaces when copying and pasting the key. If the issue persists, contact CCleaner support.
Software Won’t Activate
If activation fails, ensure that your internet connection is active. If the problem continues, contact customer support for assistance.
