Windows Defender SmartScreen prevents me from installing the app. What should I do?

Because WebCatalog is a recently released software, when you try to install WebCatalog application on Windows, it might be intercepted by the SmartScreen filter as "untrusted". Windows would show a blue warning: "Windows protected your PC - Windows Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk." like the below screenshot:

This is a false positive warning. According to Microsoft, Windows SmartScreen alerts users before running unrecognized programs downloaded from the Internet to protect users from malware. In general, SmartScreen Protection shows the above message when you try to run a newly released program or an application that has not yet established a reputation. 

In the meantime, to proceed with the installation when you receive a Windows Defender Smartscreen warning message, click on  More info:

..and click on the  Run anyway button.

Then the app will start installing on your computer.
