How to: Unblock a downloaded file (Win 11)
Files downloaded from the AFMG Download Portal that are saved to a drive formatted as NTFS need to be “unblocked” after download in order to extract them and run the setup files without errors.
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:
Important: ZIP files should be “unblocked” before their contents are extracted using Extract All... . Then run the Setup application explicitly as administrator by Right-Clicking and selecting Run as Administrator.
