Problem like with snapcomm we saw is only possible with embedded browser that fails on Kinetic load.
If you open console for browser or logs, you will see error
ERROR Error: Illegal characters in path.
Now when we know the issues, it is easy to test on user machine with the following PS command:
[System.IO.Directory]::GetFiles("\\.\\pipe\\")
If you get Exception calling “GetFiles” with “1” argument(s): “Illegal characters in path.”
then this is the same issue on this machine - some pipe with windows unsupported symbols in the name exists
