Have you ever downloaded a file from the Internet or copied it from another computer and noticed that the file doesn’t behave as expected. This is most likely the result of certain security warnings that Windows has imposed on the file as it can’t determine trust.
To solve this issue, you need to Unblock the file.
To “unblock” a file, right-click the file in Windows Explorer and choose Properties from the context menu:
Then click the Unblock button in the lower right-hand corner of the Properties dialog, and click OK or Apply:
It’s important to note that ZIP files need to be “unblocked” before their contents are extracted otherwise the contents won’t be extracted and/or behave correctly.
Enjoy!
