Did you follow the link that was shown in the error ?  
Security problem.

How did you try to start node-red ?  
What commandline ?  
Powershell ?  
Does it have admin rights ?

In powershell (admin) you can enter

```auto
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned

```

and retry. Note that this changes a security parameter on your system.

First of al: thanks!

In addition: this seems to be a policy that is different for Windows Server and normal Windows computers, and running Node Red on a normal PC seems to require changing this policy. This is something they should mention in the documentation
