2. Find CCleaner in the list and click Uninstall.

3. Restart your computer after uninstalling to ensure all remnants are cleared.

 

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

 

Step 2: Download the Latest Version of CCleaner Professional Plus

To reinstall the program, you'll need the correct installer. Here’s how:

1. Visit the official CCleaner website (search for “Download CCleaner Professional Plus” on your browser to avoid unofficial sources).

2. Look for the Professional Plus or Professional version download page.

3. Choose the installer version appropriate for your operating system and download it.

Note: Even if the download page says “Professional,” entering your Professional Plus license will unlock all the tools included in the Plus suite after installation.

 

Step 3: Install CCleaner

Once you've downloaded the installer:

1. Double-click the downloaded file.

2. Follow the on-screen instructions to complete installation.

3. When prompted, enter your license key to activate the Professional Plus features.

 

Step 4: Recover Your License Key

If you no longer have access to your original license key, don’t worry. You can recover it through these steps:

Option 1: Use the Piriform License Lookup Tool

1. Search online for “Piriform license lookup.”

2. On the official Piriform license recovery page, enter the email address you used to purchase the software.

3. You will receive an email with your license details, including the activation key.

Option 2: Retrieve from Email Receipt

If you still have access to your purchase confirmation email, your license key should be listed there. Try searching your inbox for keywords like:

• "CCleaner"

• "Piriform"

• "Cleverbridge" (the software vendor)

Option 3: Check Previous Installations (if available)

If your previous PC or backup still has CCleaner installed:

1. Open CCleaner.

2. Go to Options > About.

3. Your license name and key may be visible in that section.

 

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

 

Step 5: Activate Your License Key

After installing CCleaner:

1. Launch the program.

2. Click on Options > License Key or the Activate button on the main screen.

3. Enter your name and license key exactly as provided in your recovery email.

4. Click Register or Activate.

Once accepted, CCleaner will unlock all Professional Plus features.

 

What If Your License Key Is Invalid or Expired?

Sometimes, an error may appear saying your license is invalid. Try the following:

• Double-check for typos—license keys are case-sensitive.

• Make sure there are no spaces before or after the key.

• If your license has expired, you may need to renew your subscription via the CCleaner website.

• If problems persist, contact Piriform Support for help.

 

Optional: Reinstall Additional Tools

If you’re using CCleaner Professional Plus, you’re entitled to more tools:

• Speccy: Gives system specifications.

• Recuva: Helps recover accidentally deleted files.

• Defraggler: A disk defragmentation tool.

You may need to download each tool separately. Use the license key provided with your original purchase to activate them if needed.

 

Final Tips for a Smooth Reinstallation

• Backup your license key: Store it in a secure password manager or file for future use.

• Keep your email receipt: It’s helpful for license recovery.

• Regularly update CCleaner: The software is frequently updated to stay compatible with Windows and to patch vulnerabilities.
