Error Logging Into Web Client 2015 After Upgrade

Posted on by Microsoft Employee

After we upgraded from Dynamics GP 2013 to Dynamics GP 2015 and went through the steps in the WebClientIntallAdmin.pdf guide for upgrading web services, upon logging in we are getting the generic, "An error occurred..." error. Looking in the log, the source of the issues seems to be:

Exception Details: System.IO.FileNotFoundException: The system cannot find the file specified

File name: 'C:\GP2015\Microsoft.Dynamics.GP.Web.Services.Runtime.Process.exe' ---> System.ComponentModel.Win32Exception (0x80004005): The system cannot find the file specified

at System.Diagnostics.Process.StartWithCreateProcess(ProcessStartInfo startInfo)

at Microsoft.Dynamics.GP.Web.Services.Session.SessionProcess.StartableSessionProcess.TryToStartProcess()

at Microsoft.Dynamics.GP.Web.Services.Session.SessionProcess.StartableSessionProcess.TryToStartProcess()

at Microsoft.Dynamics.GP.Web.Services.Session.SessionProcess.StartableSessionProcess.Start()

at Microsoft.Dynamics.GP.Web.Services.Session.Service.SessionCreator.CreateSession(SessionCreationContext creationContext, Uri runtimeServiceBaseAddress, SessionUserInfo sessionUserInfo)

Indeed, the referenced file doesn't exist in the GP install directory. I have looked on another machine where the 2015 web client is installed and the .exe does exist there, so we're clearly missing something on the upgraded server, but it's not obvious to me what installer I should run through. Does anyone know?

    It turns out the Web Client Runtime wasn't selected when installing products (at some point - I didn't do it, so I'm not sure) during the actual upgrade. There was another section in the guide labeled, "Back office server preparation," that details that it should be selected. Obviously, it can also be added by adding a feature through Programs and Features in the control panel.

    Also, forgot to mention, we also completely uninstalled the Web Components and then re-installed them, but are still getting the same error. The Web Services Runtime sounds like it should be the correct thing, but they are already installed on the server in a different directory.
