Ranorex Forum

Hi,

Running Ranorex Spy (or Recorder or similar), I cannot identify any DOM objects within a page in Google Chrome. It works flawlessly with Internet Explorer.
Chrome version 66.0.3359.117 (64 bit)
Ranorex Chrome plugin version 1.1.2

I get the following error in Ranorex.Spy.log:
2018-04-19 16:23:48.395|DEBUG|Ranorex.Plugin.ChromeWebFlavor|Failed to create Chrome DOMs: System.Runtime.Remoting.RemotingException: Failed to connect to an IPC Port: The system cannot find the file specified.

Appreciate any thought on why this might be!

hi,

Have you already tried to re-instrument Chrome?
Remove the plugin and add it again using the instrumentation wizard in Ranorex Studio. (tools--> Ranorex instrumentation wizard)

Hi qwertzu,

Thanks for the reply. I did try re-instrumenting Chrome and re-installing the plug-in, but it didn't help.

In the end I uninstalled Ranorex Studio and reinstalled all pre-requisites (Visual Studio C++ redistributables) and restarted the computer. After that it worked. It might have been that I previously was missing VC++ 2015, or it might have been something else. A reinstall solved it either way.

Cheers,
Kalle
