Couldn't find type for class NLog.NLogTraceListener, NLog



I have installed community edition of UI Path recently . I have activated the free trial . When trying to run a simple project, I get the following error. Please help on this.

Couldn’t find type for class NLog.NLogTraceListener, NLog.

It looks like a required package is not installed.
Go to Setup->Manage Packages and check if all available packages are installed


Hi Dimitrious,

I couldnt find Setup --> Manage Packages in my UI path console. Could you please help on how I should move further on this.



Sorry, my mistake you will find it here (the icon with the opened box):

Email option couldn't able to find

Hi Dimitry,

I have installed the following packages. Now I get an error “System.Exception: Could not connect to UiPath Robot Service. Make sure the service is started!” . I could see I am unable to start the UI path Robot service as the Start button is disabled.



Hello again,

You need to have the UiPath platform installed. The community edition only contains the design studio and NOT the Ui Robot!
You can find it in UiPaths download page.
