How to use unblock-file command in PowerShell to unblock a file type?

Question

I'm trying to install a file with the extension .msi but I'm seeing an error that says "system administrator has set policies to prevent installation of this file type". Can someone explain how to use the unblock-file command in PowerShell to unblock this file type?

Answer 1

SMH. Not a PowerShell problem. Ask your AD Domain admin.

Answer 2

Hi,

Please note the Unblock-File cmdlet only unblocks files that you downloaded from the internet. You need to contact your system administrator if group policies block the MSI files.
