Add-Type : Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information

This tutorial, we will discuss how to fix error, Add-Type : Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

Recently I was trying to work with PowerShell to connect to SharePoint Online. But I got the error which says: Add-Type : Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

Basically, we were trying to use Microsoft.SharePoint.Client.dll and Microsoft.SharePoint.Client.Runtime.dll in PowerShell as below.

Add-Type -Path ‘E:\Bijay\Microsoft.SharePoint.Client.dll’
Add-Type -Path ‘E:\Bijay\Microsoft.SharePoint.Client.Runtime.dll’

But when we run the command, it gave the error like below:

Add-Type : Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more
information.

Add-Type : Unable to load one or more of the requested types

The dlls were creating the problem here. So I replace the above dlls with new dlls from the 16 hive folder.

After this, you will not get the error Add-Type : Unable to load one or more of the requested types.
