CCleaner Pro: Step-by-Step Instructions
Before installing the program, be sure to temporarily disable your antivirus!
This is necessary for the installation file to work correctly – the antivirus may mistakenly block the launch or delete parts of the program. After installation, do not forget to turn the protection back on.
Where to Download CCleaner Pro

Always download CCleaner Pro from official sources. The safest place is the official Piriform website (now owned by Avast). Be wary of third-party download sites that might bundle unwanted software with your installation. The official CCleaner Pro includes a 14-day trial, after which you’ll need to purchase a license to continue using the premium features.
Installation Process
The installation itself is straightforward:
- Double-click the installer file you downloaded
- Select your preferred language
- Choose between “Install for all users” (requires admin rights) or “Install for current user only”
- Select your installation directory or use the default location
- Wait for the installation to complete
- Launch CCleaner Pro when prompted
Common Installation Errors and Solutions
You might encounter these issues during installation:
- Error 1303: Insufficient permissions – Try running the installer as administrator
- Installation freezes: Close the installer, restart your computer, and try again
- Error 1722: Problem with Windows Installer package – Download a fresh copy of the installer
- “Application cannot be installed”: Check if you have adequate disk space and administrative privileges
Verifying Successful Installation

After installation, you should verify that CCleaner Pro is working correctly:
- Launch CCleaner Pro from your desktop or Start menu
- Check the top-right corner of the application – it should say “CCleaner Professional”
- Click on “About” to verify your license status
- Run a quick system scan to ensure the software can analyze your system
If the scan completes without errors, congratulations – you’ve successfully installed CCleaner Pro!

My Personal Experience with CCleaner Pro
I’ve been using CCleaner in various forms for over eight years, upgrading to Pro about three years ago when my aging laptop started showing signs of slowdown. The decision to upgrade came after comparing the performance benefits against the subscription cost.
Tasks I Use CCleaner Pro For
In my day-to-day usage, I primarily rely on CCleaner Pro for:
- Weekly automatic system cleaning to keep my work computer running smoothly
- Quarterly deep cleaning sessions before important projects
- Managing startup programs to reduce boot time
- Finding and removing duplicate files when my storage runs low
- Keeping browser performance optimal by clearing accumulated cache files
What I’ve found most valuable is the automatic scheduling feature. Unlike the free version, I don’t have to remember to run cleanup sessions manually. This “set it and forget it” approach ensures my system never gets bogged down with temporary files.
Previous Experience with Alternatives
Before settling on CCleaner Pro, I tried several alternatives:
- Windows built-in Disk Cleanup – Too basic for my needs
- Avast Cleanup Premium – Good but had resource-heavy background processes
- Wise Disk Cleaner – Decent free option but lacked advanced features
- BleachBit – Powerful but less user-friendly interface
Pros and Cons From My Experience
After years of usage, I’ve identified these strengths and weaknesses:
Pros:
- Intuitive interface that’s easy to navigate
- Noticeable performance improvement on older systems
- Regular updates with new features
- Low system resource usage
- Effective at reclaiming disk space
Cons:
- Subscription model rather than one-time purchase
- Some features could be more aggressive in cleaning
- Occasional false positives in registry cleaning
- Software updater sometimes misses niche programs
- Premium features could offer more differentiation from free version
CCleaner Pro vs. Alternatives: Detailed Comparison
Feature | CCleaner Pro | Avast Cleanup | System Mechanic | Windows Built-in Tools |
---|---|---|---|---|
Price | $24.95/year | $39.99/year | $49.95/year | Free |
Automatic Cleaning | Yes | Yes | Yes | Limited |
Registry Repair | Comprehensive | Basic | Advanced | No |
Software Updater | Yes | Yes | Limited | No |
Resource Usage | Low | Medium | High | Very Low |
Privacy Tools | Extensive | Good | Limited | Basic |

While CCleaner Pro isn’t the most feature-rich option, it strikes an excellent balance between functionality, system resource usage, and price. For most users, it provides the best value proposition unless you need the specialized features of more expensive alternatives.
Frequently Asked Questions
Conclusion: Is CCleaner Pro Right for You?
After years of using CCleaner Pro, I can confidently say it delivers on its core promise of keeping your system running smoothly with minimal effort on your part. The automatic scheduled cleaning alone justifies the cost for many users, as it eliminates the need to remember to perform regular maintenance.
The Pro version particularly shines for:
- Busy professionals who can’t afford system slowdowns
- Older computers that need regular maintenance to perform well
- Users who prefer a “set it and forget it” approach to system care
- Anyone who values their time more than the modest subscription cost
While there are free alternatives available, CCleaner Pro’s combination of ease of use, effectiveness, and modest system requirements makes it a worthwhile investment for many users. Just remember that no optimization software can overcome fundamental hardware limitations or replace good computing habits.
Whether you choose CCleaner Pro or another solution, regular system maintenance is essential for keeping your computer performing at its best. Based on my experience, CCleaner Pro makes that maintenance process as painless as possible.
