Fix Blocked Apps and Software Installation in Windows 10

Just recently, I had needed to use data card temporarily in place of my broadband connection. But when I began to install the data card software in Windows 10, an error message appeared on the screen, "This app has been blocked for your protection". The reason is, of course, the publisher is not trusted!!! I was appalled by seeing this error message because the data card manufacturer is D-Link. And I really don't think that D-Link comes under non-trusted publisher’s category. After all, it is one of the top most brands in the hardware and network vendors.

Well, I found a solution to this problem. And I think, many of you may have also encountered such problem, or it could happen in the future. And you may need to address this issue. So now I'm going to tell that how this problem can be dealt.

Main cause of Windows 10 Apps and Software Installation Blocked Error:

This problem is primarily due to the SmartScreen feature of Windows 10. Windows 10 is very strict in terms of security. If Windows 10 seems to have an unauthorized App or Software on the system and that cannot be trusted. In that case, Windows 10 does not allow you to install that particular App or Software. This is to protect you from the unknown threats and it is a must-have feature. But the problem occurs when it also blocks the applications and software from an installation which are not dangerous at all. Take example of my case, D-Link's data card. Whose software is inbuilt, and this model is just 2 years old maximally. But Windows 10 does not allows to install it. It's all just because the driver software of this model of D-Link data card is not signed.

How to Resolve Windows 10 Apps and Software Installation Blocked Error:

To overcome the problem of blocked apps, software and drivers Installation in Windows 10, the first thing you can do is the updation. Update it to the latest version or simply download the latest version. But if the latest version of that app, software or driver is not available, then? Then you must stop the SmartScreen in Windows 10.
So, let's start.

Disable the SmartScreen in Windows 10 to Allow the Apps Installation:

Step 1: Right Click on the Start and open 'Control Panel'.
Or you can also open the 'Control Panel' from the 'Keyboard Shortcut'. Just press Win + R + P and see the magic.

Step 2: In the Control Panel, search for 'Security and Maintenance' and open it.

If you don't get 'Security and Maintenance' option there, then you are probably viewing the Control Panel items in 'Category Mode'. Change it to 'Large icons' or 'Small Icons' from the top-right side in the control panel window. Or you can also select and open 'Find and fix problems' under the 'System and Security' category. Then select and open 'Security and Maintenance' from the bottom-left in the newly opened window.

Step 3: Now on the left side of Security and Maintenance Window, you can see the option 'Change Windows SmartScreen Settings'. Just click and open it, then allow when UAC asks you.

Step 4: Now 'SmartScreen Window' will be opened with 3 available options. Select the last one 'Don't do anything (turn off Windows SmartSceen)'. And then click 'OK'.

Restart your system and then install the app which was causing the problem while installation. Now check whether the problem is resolved, or not.

What? No, still unable to install the app again.

OK, do not worry about, we have another way to get out of this.
Now you will have to enable the built-in Administrator account in order to install the blocked app. Follow the steps given below.

5 Steps to enable the built-in Administrator Account of Windows 10:

Step 1: Right Click on Start and open 'Computer Management'.

Tip: You can also open this 'Secret Start' using the 'Keyboard Shortcut'. Make sure to try once, just press Win + X .

Step 2: You can see the option 'Local Users and Groups' on the left panel of 'Computer Management' Window. Now navigate to -

 
Computer Management (Local)>System Tools>Local Users and Groups>Users

I mean, Open 'System Tools', then 'Local Users and Groups', and then 'Users'.

Step 3: Now you can see all the accounts of your Windows 10 listed there. Right click on the 'Administrator' account and open its properties.

Step 4: Simply uncheck mark the option "Account is Disabled", in the 'Administrator Properties Window'.

Step 5: Now 'Apply' and 'OK'. Then close the 'Computer Management' window and restart your computer.

Step 6: After the computer restarts, sign in as the Administrator (the account you have just enabled).

Now install the blocked application again, which was giving the error. And I'm pretty sure that this time there would be no problem with it. The problem with my Data card installation solved too, by following these steps. As you can see in the below picture.
