How do I stop Windows from blocking my installation of PC Cleaner?

This depends on your version of PC Cleaner, your Windows Store settings, or which antivirus program you use. These are the three main reasons why Windows might block your attempt to install PC Cleaner.

Do you use PC Cleaner version 8 or below?

If yes, these older versions of PC Cleaner for Windows are not compatible with the most recent versions of Windows 11.

We recommend you download the latest version of our app to fix this issue:

Download the latest version of PC Cleaner

Does your version of Windows 10 or 11 only allow apps from the Microsoft Store?

If either one of the messages below appears when you try to install PC Cleaner, this means you need to change your Windows settings so you can buy or download software for free from elsewhere:

1. The app you're trying to install isn't a verified app from the Store

2. You can only install apps from the Microsoft Store

How to change this Windows setting:

• Go to Settings > Apps > Apps & Features in Windows.
• Change your Installing Apps setting from Allow apps from the Store only to one of these two options below. The second of the two means that Windows doesn't ask for your permission when you choose to download software:

1. Warn me before installing apps from outside the Store

2. Allow apps from anywhere

Choosing the setting Warn me before installing apps from outside the Store means you will still get the following message from Windows:

The app you're trying to install isn't a verified app from the Store 

• When it appears, click Install Anyway to continue.

Does your antivirus software flag PC Cleaner as "risky" software?

Some antivirus apps flag new PC Cleaner releases as risky. This is because the analysts working on these apps haven't necessarily had the chance to look at them in detail. Software companies usually correct this type of problem within 12-72 hours, depending on which antivirus app you have and the brand.
