Hello I really need help

When I want to debug the code I get this error

Error 1 The type or namespace name 'AxACTIVEHAPTEKXLib' could not be found (are you missing a using directive or an assembly reference?) C:\Users\new\Downloads\gnututor_0.1\GnuTutor\GnuTutor\Interface.cs 44 17 GnuTutor

and also this one

Warning 2 Cannot load type library for reference "ACTIVEHAPTEKXLib". Library not registered. (Exception from HRESULT: 0x8002801D (TYPE_E_LIBNOTREGISTERED)) GnuTutor

Can you help me with this?

Many thanks

I've put some more info re this on the website's documentation link.

Here's some more info
There are a couple of options for agents.

The error you are getting now is connected to the default choice of agent, the Haptek Player.

You have 2 options.

1. Remove this agent and all references to it. That includes the troublesome library you mentioned. I have examples/code for this on the website under the documentation link. Look for the attachments.

2. Install the agent. This will require a Windows platform and installing the software here:

http://www.haptek.com/dist/4.11/happlayer41140/happlayer41140.exe

This should register the activex component take care of the problem.

Please let me know if you have any more problems.

Hi,

I am attempting to build an ITS using the GnuTutor framework.

I elected to use XFace as the agent and cannot get it to connect. I am in Visual Studio 2019.

I get the following Output:

Couldn't connect to XFacePlayer. Make sure it's in server mode

I have tried connecting XFaceClient to localhost 50011 but every attempt cannot establish connection to server.

Is there anything I can do? Will I eventually get a connection to server?

I appreciate any guidance on this.

Here is the current home for the project:

You are more than welcome to use GnuTutor for any project. However, you should know that as 10-year old code, it no longer runs readily on Windows. It can run with some help that I outline in the link above.

Also, it was an experiment in dialogue management using Prolog. I've found this to be a nontrivial barrier for some users. No other AutoTutor system before or after GnuTutor has used Prolog this way.

A couple of years ago, I wanted to combine GnuTutor with Guru and blend in some ideas of model tracing and constraint-based tutoring. I suddenly got busy with a new grant and haven't gotten back to it, unfortunately.

If you are interested, I'll let you know when I pick that back up.

Specifically to your question, the error message seems pretty clear: "Couldn't connect to XFacePlayer. Make sure it's in server mode"

This suggests to me that the problem is XFacePlayer. I recommend making sure that is working independent of GnuTutor before trying to connect to it.

If you do establish XFace is working, but GnuTutor can't connect to it, AND you are on Windows, I'd suggest checking your firewall.

The link above also shows how you can test GnuTutor independently of the agent clients, in case you want to verify that GnuTutor is working independently.
