Windows Security Message: These files can’t be opened
When attempting to open a file, a Windows security message appears:
’These files can’t be opened’
This behavior can occur when attempting to open a file that has been downloaded from the Internet or otherwise copied from another computer. Windows sometimes places a security block on the file, preventing it from being opened.
If the file is from a reputable source, unblock the file using the steps below.
- Locate the file using Windows Explorer.
- Right click on the file and select Properties. A file properties window will open.
- On the general tab of the file properties window, check the Unblock check box and click OK.
- Run the file again. The Windows security issue should be resolved.
