I am trying to require a .net assembly and keep coming across this  
message.  
The assembly is not on a network location, so I’m not sure why it’s  
upset.  
I can likely fix this by building the project from source, but-- any  
ideas  
on how to fix this if I couldn’t?

Below is the error message.

(ir):1:in `require’: An attempt was made to load an assembly from a  
network  
location which would have caused the assembl  
y to be sandboxed in previous versions of the .NET Framework. This  
release  
of the .NET Framework does not enable CAS pol  
icy by default, so this load may be dangerous. If this load is not  
intended  
to sandbox the assembly, please enable the l  
oadFromRemoteSources switch. See  
[\<loadFromRemoteSources\> Element | Microsoft Learn](http://go.microsoft.com/fwlink/?LinkId=155569) for more information.  
(LoadError)
