How to fix Remote Desktop Connection invalid connection file?
Actually, the cause of this error is not specified clearly. But still, we can provide three tested methods to help you troubleshoot the Remote Desktop Connection Invalid connection file specified problem you may encounter when remotely controlling another computer via RDP.
Method 1. Launch the file manually
One method to solve the Invalid connection file RDP error temporarily is to launch the file manually. According to feedback from some users, they received the Invalid connection file notification, but successfully open it in the drive where the file locates. For example, when the error is: Invalid connection file (Name\AppData\Local\rdclientwpf\xxxxxxx\xxxxx.rdp) specified. You can open the file in C:\Users\User Name\AppData\Local\rdclientwpf\xxxx\xxxx.rdp, it will work normally then.
Method 2. Delete the user profile and log in again
Since there’s a problem with the connection file stored before, then the solution we suggest here is to delete the RDP file on the session client and delete the user profile on the session host if it even created one and try logging in again to see if Remote Desktop Connection Invalid connection file error solved.
Method 3. Run SFC scan
