When you want to add an assembly from a network UNC share using the command:

$scriptPath = Split-Path ($MyInvocation.MyCommand.Path)
Add-Type -path "$scriptPath\selenium-dotnet\net40\WebDriver.dll"

you might face such an error:

Add-Type: Could not load file or assembly 'file:///Z:\A-Backup\Users\Administr
ator\Desktop\MAXIMO Automatic\selenium-dotnet\net40\WebDriver.dll' or one of it
s dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515

How can I fix this problem?

Answer 1

The key is to allow for loading an assembly from a network path for a PowerShell executable. It can be done by creating the two files

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe.config C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe.config

and paste this code:

<?xml version="1.0" encoding="utf-8" ?> 
<configuration>
   <runtime>
      <loadFromRemoteSources enabled="true"/>
   </runtime>
</configuration>
