Entra AD Connect System.NotSupportedException: The given path's format is not supported

Question

Hello everyone,

I am trying to use swing migration to upgrade my existing Azure Active Directory Connect application. I am unable to run the Microsoft Entra Active Directory Connect V 2.4.1.131.0 setup without receiving the following error message. I am currently running the service on Windows Server 2016. I have installed a brand new Windows Server 2022 standard server. I have met all the prerequisites for Azure AD Connect. I am getting the same error on both the old and new servers. I used the links below for the setup. I have attached the log file created when the service failed.

Use a swing migration to upgrade

The solution in this link did not work for me.
