Error while Opening AX 2012 R2 Retail POS: could not load all external service modules

Posted on by Microsoft Employee

When I setup device information on hardware profile and run the N-jobs, the following error appears on POS screen and it won’t let me open POS:

Connector TestConnector not found!

SystemCore: System.Exception: Processor not found.

    Copy the Microsoft.Dynamics.Retail.TestConnector.dll from C:\Program Files (x86)\Microsoft Dynamics AX\60\Client\Bin\Connectors to C:\Program Files (x86)\Microsoft Dynamics AX\60\Retail POS\Connectors.

    Try to open POS again
