When you open a copy of project files from a remote location / downloaded from the internet you get the message that the project location is not trusted:
or a security warning when opening the project warning that the project file may have come from a location that is not fully trusted:
First assure yourself that the files you downloaded are from a trustworthy source. If this is the case then you could remove the warnings from these files like this:
Unblock downloaded files in folder including subfolders:
gci -path “C:\BeeHive” -recurse | Unblock-File (replace “C:\BeeHive” with the folder in which you want to unblock all files)
