Failed to connect to an IPC Port: The system cannot find the file specified.

[f3xx]

Some users of my application are experiencing an issue with IPC setup with EasyHook. The error is detailed below.

Other users are experiencing no problems at all and so I guess this could be a permissions error where the user does not have permission to set up named pipe IPC?

What would be the best steps to diagnose / resolve? Are there minimal requirements for IPC?

Thank you

Pretty sure a permission issue will give you an access denied message.

I would debug further to determine that the channel is actually open, it doesn't sound like an issue with EasyHook. Perhaps a simple test app(s) that setup and use IPC as a sanity check?
