The most efficient way to deal with the block would be using Command Prompt. Windows 10 intentionally blocks installations of suspicious programs for inexperienced users in order to prevent possible system damage. Furthermore, you will get the same error after trying to run the installer as administrator. Then you will see information explaining that the app was blocked according to the administrator policy on this computer, plus details about the name, publisher, and location of the blocked app installer.ĭespite the fact that this error message is sent by the UAC service, you cannot allow the installation by simply disabling protection settings in UAC or changing them to minimal. That message is sent by the User Account Control (UAC). When you are launching an app Windows sees as potentially dangerous, it immediately aborts the installation and block that app, then alerts you with the appropriate message.
How to fix “this app has been blocked for your protection”? Another possible reason for the block – expired installer certificates and wrong digital signatures of the app you want to install.
It happens, for example, when you need to install old drivers for your laser printer – the system thinks they are outdated, thus dangerous due to expired service support from the manufacturer (even though your printer is fully operational). However, sometimes even installers downloaded from official or trusted sources are getting blocked by the system without any significant reasons.
In case, you cannot find an official source, you should probably stay away from the suspicious software. If it so, we recommend you to download the software you need from the official website. It is highly likely that you have downloaded it from a random website. Try to remember how you got that installer file that is causing the problem. The first thing to do when you see the “This app has been blocked for your protection” error message, is to stop for a moment and retrace your steps.
Windows 10 even analyzes driver signatures, checks digital certificates, monitors multiple accounts on the same PC, and much more. Latest versions of this OS use advanced scanning algorithms, so the risk of installing/running potentially dangerous programs and malware is minimized.
In most cases, Windows’ behavior is fully justified, and you should not perform any actions to trick the system. Of course, such measures are meant to increase your safety and protect the system from malicious code, but what to do, when you know that software is ok and you really need it for your work? In today’s articles, we are going explain core principles of Windows 10 app-blocking mechanism and tell you how to fool the system. Advanced protection is good to have, but sometimes it works against the user – when you cannot install an app just because Windows thinks it is not safe. One of the most distinctive features of Windows 10 is its high-security requirements and strict user protection policy, which is active by default.
