"Failed to acquire a license. Please restart the product." in Vault API

Anonymous — Thu, 10 Oct 2019 11:43:01 GMT

OS: Windows10 (64bit)

License: Single User(Standalone License).

Vault Server: Autodesk Data Management Server Console 2020

Vault Client: Autodesk Vault Workgroup 2020

---

I am making a program to login Vault 2020 with Vault API.

following code is sample program to login Vault client.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;

using VDF = Autodesk.DataManagement.Client.Framework;
using Autodesk.DataManagement.Client.Framework.Vault.Currency.Connections;

namespace VaultFormSample
{
    static class Program
    {
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);

            Connection conn = VDF.Vault.Forms.Library.Login(null);

            Application.Run(new Form1());
        }
    }
}

Run it, then I got an following error at a login session.

What is the cause of this error? I can login Autodesk Vault Workgroup 2020 and Autodesk Data Management Server Console 2020 via Applications.

What should I do to eliminate this error?

Best regards.

Most likely you missed including the licensing (AdskLicensingSDK_2.dll) into your project. You need to copy this library also to the output folder. Compare the SDK sample template "API-Onboarding-ConsoleApp" on how to do this.

Thank you for your advise.

I copied "C:\Program Files\Autodesk\Autodesk Vault 2020 SDK\bin\x64\AdskLicensingSDK_2.dll" to my project ("C:\Program Files\Autodesk\Autodesk Vault 2020 SDK\VS17\CSharp\VaultFormSample\VaultFormSample\bin\Debug\"), then it was able to login! thank you.
