To make it work without modifying your scripts:

I found a solution here: http://wahlnetwork.com/2015/11/17/solving-the-first-launch-configuration-error-with-powershells-invoke-webrequest-cmdlet/

The error is probably coming up because IE has not yet been launched for the first time, bringing up the window below. Launch it and get through that screen, and then the error message will not come up any more. No need to modify any scripts.

It is sure because the Invoke-WebRequest command has a dependency on the Internet Explorer assemblies and are invoking it to parse the result as per default behaviour  As Matt suggest  you can simply launch IE and make your selection in the settings prompt which is popping up at first launch  And the error you experience will disappear    But this is only possible if you run your powershell scripts as the same windows user as whom you launched the IE with  The IE settings are stored under your current windows profile  So if you  like me run your task in a scheduler on a server as the SYSTEM user  this will not work   So here you will have to change your scripts and add the -UseBasicParsing argument  as ijn this example   WebResponse   Invoke-WebRequest -Uri  url -TimeoutSec 1800 -ErrorAction Stop -Method Post -Headers  headers -UseBasicParsing

In your invoke web request just use the parameter -UseBasicParsing e g  in your script  line 2  you should use   rss   Invoke-WebRequest -UseBasicParsing  According to the documentation  this parameter is necessary on systems where IE isn t installed or configured  Uses the response object for HTML content without Document Object Model  DOM  parsing  This parameter is required when Internet Explorer is not installed on the computers  such as on a Server Core installation of a Windows Server operating system

You can disable need to run Internet Explorer s first launch configuration by running this PowerShell script  it will adjust corresponding registry property   Set-ItemProperty -Path  HKLM  SOFTWARE Microsoft Internet Explorer Main  -Name  DisableFirstRunCustomize  -Value 2   After this  WebClient will work without problems

Yet another method to solve  updating registry  In my case I could not alter GPO  and -UseBasicParsing breaks parts of the access to the website  Also I had a service user without log in permissions  so I could not log in as the user and run the GUI   To fix    log in as a normal user  run IE setup  Then export this registry key  HKEY USERS S-1-5-21-     SOFTWARE Microsoft Internet Explorer In the  reg file that is saved  replace the user sid with the service account sid Import the  reg file   In the file

I have had this issue also  and while -UseBasicParsing will work for some  if you actually need to interact with the dom it wont work  Try using a a group policy to stop the initial configuration window from ever appearing and powershell won t stop you anymore  See here https   wahlnetwork com 2015 11 17 solving-the-first-launch-configuration-error-with-powershells-invoke-webrequest-cmdlet   Took me just a few minutes once I found this page  once the GP is set  powershell will allow you through
