Getting "Could not parse the language" exception while publishing

Question

While publishing the content in sitecore, the following error occured.

Job started: Publish to 'web'|#Exception: System.Reflection.TargetInvocationException:

While checking on logs, i found the error with following language

Could not parse the language 'ms-BD'. Note that a custom language name must be on the form: isoLanguageCode-isoRegionCode-customName.

But that language is not installed, and there are no language corresponding to that code.

UPDATE #1: Add some more log details:

Looks like you are trying to use culture 'ms-BD' that is not present in .NET by default. Check that you definitely need 'ms-BD' and it is not mistake or misprint.

You can check cultures registered in system by running this C# console app:

class Program
{
    static void Main(string[] args)
    {
        CultureInfo[] cinfo = CultureInfo.GetCultures(CultureTypes.AllCultures & ~CultureTypes.NeutralCultures);
        Console.WriteLine("List of cultures registered in system");
        foreach (CultureInfo cul in cinfo)
        {
            Console.WriteLine(cul.DisplayName + "  " + cul.Name);
        }
        Console.ReadLine();
    }
}

I get next cultures:

• Malay ms
• Malay (Brunei Darussalam) ms-BN
• Malay (Malaysia) ms-MY
• Malay (Latin, Singapore) ms-SG

But you are trying to use 'ms-BD'. Malay (Bangladesh)? If it is not misprint/mistake and you are intended to use 'ms-BD' then you need to register your custom culture:

class Program
{
    static void Main(string[] args)
    {
        string culture = "ms-BD";
        string name = "Malay Bangladesh";

        CultureInfo cultureInfo = new CultureInfo("ms");
        RegionInfo regionInfo = new RegionInfo("BD");

        CultureAndRegionInfoBuilder cultureAndRegionInfoBuilder = new CultureAndRegionInfoBuilder(culture, CultureAndRegionModifiers.None);

        cultureAndRegionInfoBuilder.LoadDataFromCultureInfo(cultureInfo);
        cultureAndRegionInfoBuilder.LoadDataFromRegionInfo(regionInfo);

        // Custom Changes
        cultureAndRegionInfoBuilder.CultureEnglishName = name;
        cultureAndRegionInfoBuilder.CultureNativeName = name;

        cultureAndRegionInfoBuilder.Register();
    }
}

After running this console application on machine where exception was occurred you will get new custom culture that should fix exception.
