Please refer the below steps.
- Download the Sysinternals Suite ( https://docs.microsoft.com/en-us/sysinternals/downloads/sysinternals-suite )
- Extract the zip to a folder
- Run a CMD as administrator
- Navigate to the folder Sysinternals has been extracted to
- Run the following command: handle net.pipe
Running this command should display a list of processes that use named pipes and the address they listen to, e.g.:
PAD.BrowserNativeMessageHost.exe pid: 21064 type: Section 464: \Sessions\1\BaseNamedObjects\net.pipe:EbmV0LnBpcGU6Ly8rL0JST1dTRVJOQVRJVkVIT1NULzE2NjIwLzEv
Microsoft.Management.Services.IntuneWindowsAgent.exe pid: 26708 type: Section 6AC: \BaseNamedObjects\net.pipe:EbmV0LnBpcGU6Ly8rL0lOVFVORU1BTkFHRU1FTlRFWFRFTlNJT04vU1RBVFVTU0VSVklDRS8=
PipesTest.Server.exe pid: 6540 type: Section 3AC: \BaseNamedObjects\net.pipe:EbmV0LnBpcGU6Ly8rLw==
You need to identify whether there is a process displaying the string highlighted in bold (EbmV0LnBpcGU6Ly8rLw==).
If such a process has been found, please make sure PAD is closed (from the taskbar as well), kill the process identified in previous step and try again to start PAD.
I hope above will help you.
