    Hi Jinhui,

    This could be a problem related to your network. Are you using a remote server or your own machine as the server?

    Best regards,

    • The code as below:

      int retCode = 0;

      string connStr = "";

      B1WizardBase.B1Connections.ConnectionType cnxType = B1WizardBase.B1Connections.ConnectionType.SSO;


      string addOnIdentifierStr = null;

      if ((System.Environment.GetCommandLineArgs().Length == 1)) {

      connStr = B1Connections.connStr;


      else {

      connStr = System.Environment.GetCommandLineArgs().GetValue(1).ToString();


      try {


      retCode = B1Connections.Init(connStr, addOnIdentifierStr, cnxType);


      if ((retCode != 0)) {

      System.Windows.Forms.MessageBox.Show("ERROR - Connection failed: "+ B1Connections.diCompany.GetLastErrorDescription());



      // CREATE DB

      if (((cnxType == B1WizardBase.B1Connections.ConnectionType.SSO)

      || (cnxType == B1WizardBase.B1Connections.ConnectionType.MultipleAddOns))) {

      COINV_Db addOnDb = new COINV_Db();



      // CREATE ADD-ON

      COINV addOn = new COINV();



      catch (System.Runtime.InteropServices.COMException com_err) {

      // HANDLE ANY COMException HERE

      System.Windows.Forms.MessageBox.Show("ERROR - Connection failed: " + com_err.Message);

    Hi all,

    I've got exactly the same issue. Sometimes the addons are starting up without any problem, sometimes I get this error:

    Error : -126

    Invalid license server address; make sure the DI configuration file (b1-local-machine.xml) exists and is valid.

    The result is that the user has to start or restart all Addon manually using the Add-On Manager, which is annoying.

    I'm using Windows Server 2008 R2, Citrix XenApp6.0 and SAP Business One 8.82 PL09.
    Interesting is that before we did the B1 update to 8.82 (from 8.81) everything worked great!

    I already reinstalled B1 on the affected systems. No success.

    License server name or IP doesn't make any difference.

    I have no more idea, how to solve this problem.

    I'm looking forwar to any hint.

    • Hi,

      We just had this issue and managed to resolve it - hope this helps someone.

      Client was 8.8 (all users on Terminal Services) and had several add-ons running (standard SAP add-ons, B1UP, custom add-on etc).

      Out of the blue they reported that none of the add-ons were connecting and they were getting the error:

      Connection Failed Error: Invalid license server address;make sure the DI configuration file(b1-local-machine.xml) exists and is valid

      What we discovered was that an internal IT person had registered the 8.82 di api SAPBobsCom dll on that TS box but not in the normal location. I guess that the system is expecting the xml file in the same location as the registered dll. Once we registered the correct 8.8 dll all connected OK again.
