Hello folks,

the corresponding decompiled C# code that Wine-Mono fails on:

--- snip ---
// Type: GVMP_Launcher.Functionality.Keygen
// Assembly: GVMP-Launcher, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=null
// MVID: 6CDBBCAC-058D-4670-8736-86E3F4358FEC
// Assembly location: Z:\home\focht.wine\drive_c\Program Files (x86)\GVMP -
Launcher\GVMP-Launcher.exe

using System.Management;
using System.Security.Cryptography;
using System.Text;

namespace GVMP_Launcher.Functionality
{
  public class Keygen
  {
    public string GenerateKey(string p_ForumID, string p_Name)
    {
      ManagementObjectCollection objectCollection = new
ManagementObjectSearcher("Select ProcessorId From Win32_processor").Get();
      string str = "";
      using (ManagementObjectCollection.ManagementObjectEnumerator enumerator =
objectCollection.GetEnumerator())
      {
        if (enumerator.MoveNext())
          str = enumerator.Current["ProcessorId"].ToString();
      }
      using (SHA256 shA256 = SHA256.Create())
      {
        byte[] hash = shA256.ComputeHash(Encoding.UTF8.GetBytes(str + p_ForumID
+ p_Name));
        StringBuilder stringBuilder = new StringBuilder();
        for (int index = 0; index < hash.Length; ++index)
          stringBuilder.Append(hash[index].ToString("x2"));
        return stringBuilder.ToString();
      }
    }

public Keygen()
    {
      base.\u002Ector();
    }
  }
}

        if (ConfigurationManager.AppSettings["user_key"] == null)
        {
          configuration.AppSettings.Settings.Remove("user_key");
          configuration.AppSettings.Settings.Add("user_key",
keygen.GenerateKey(ConfigurationManager.AppSettings["forum_id"],

There is an update of Wine-Mono from 4.9.4 to 5.0.0 in upcoming Wine 5.7
release.

You might want to recheck then.
