D-Link application error: This app has been blocked for your protection

Microsoft Windows 10 has advanced security features. If any program has an invalid certificate or security issue, then the program will be blocked and can’t be run on Windows 10. Or a similar problem is occurring with D-Link modem on Windows 10. I have a DWP-157 21 Mbps Wireless Data USB Modem, which was working fine on Windows 7 and Windows 8 or 8.1.

I have recently bought an Asus A555L Laptop, and it does not come with any OS, Due to this, I had the need to install an operating system. So I installed Windows 10 and after installation Laptop was working fine but when as soon tried to connect the D-Link DWP 157 modem. The following error I received:

“This app has been blocked for your protection”

“An Administrator blocked you from running this app. For more information, contact the Administrator.”

I have searched online, there are lots of solution available, but any solution was not fully working with my D-Link 157 USB Modem. Mean, I had installed the software using the online trick. But was not able to use the Dlink application software and modem. I could not go back to Windows 7 because of drivers incompatibility problem and don’t want to buy another Modem.

So I did something different. After trying too many methods finally found a manual solution to my problem. And now I can use the modem on Windows 10. How I solved my problem read the process below:
