The application is distributed as a zip file. By default, on Windows, zip files downloaded from the Internet, including all files inside, are "blocked" by the operating system. This means the application and DLL files may become unusable.
To use the application without issues, the zip file should be unblocked first before extracting its contents out. To “unblock” a file, right-click it in Windows Explorer, choose Properties from the context menu, click the Unblock button in the lower right-hand corner of the resulting dialog, and hit OK or Apply
You can now extract the content of the zip to a destination of your choice.
Windows includes a SmartScreen filter that prevents unknown programs from running.
SmartScreen is a security feature that will prevent bad applications from running, but it also prevents unknown legitimate applications from running. Windows sends and retrieves information about every application you download and install. If the application is known, Windows will run the application.
If SmartScreen doesn’t know about an application, like a new or niche program that few people use, Windows will prevent the application from running on your computer. This will be the case with Gulden Trade Ticker.
When you try to launch the application for the first time, Windows will display a message saying it "protected your PC" by preventing the application from running. Click the More info link. Click the Run anyway button and Windows will allow the application to run.
