Visual Basic Version:

Private Sub setRegisterForWebBrowser()

    Dim appName = Process.GetCurrentProcess().ProcessName + ".exe"
    SetIE8KeyforWebBrowserControl(appName)
End Sub

Private Sub SetIE8KeyforWebBrowserControl(appName As String)

    Dim Regkey As RegistryKey = Nothing
    Dim lgValue As Long = 8000
    Dim strValue As Long = lgValue.ToString()

    Try

    Catch ex As Exception


        MessageBox.Show("Application Settings Failed")
        MessageBox.Show(ex.Message)

    Finally

        'Close the Registry

Rather than changing the RegKey, I was able to put a line in the header of my HTML:

<html>
    <head>
        <!-- Use lastest version of Internet Explorer -->
        <meta http-equiv="X-UA-Compatible" content="IE=edge" />

        <!-- Insert other header tags here -->
    </head>
    ...
</html>

See Web Browser Control & Specifying the IE Version.

just adding the following to your html does the trick no need for registry settigns
```
<meta http-equiv="X-UA-Compatible" content="IE=11" >
```

You can try this link

try
{
    var IEVAlue =  9000; // can be: 9999 , 9000, 8888, 8000, 7000
    var targetApplication = Processes.getCurrentProcessName() + ".exe"; 
    var localMachine = Registry.LocalMachine;
    var parentKeyLocation = @"SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl";
    var keyName = "FEATURE_BROWSER_EMULATION";
    "opening up Key: {0} at {1}".info(keyName, parentKeyLocation);
    var subKey = localMachine.getOrCreateSubKey(parentKeyLocation,keyName,true);
    subKey.SetValue(targetApplication, IEVAlue,RegistryValueKind.DWord);
    return "all done, now try it on a new process".info();
}
catch(Exception ex)
{
    ex.log();
    "NOTE: you need to run this under no UAC".info();
}

It is best to force the highest mode possible. That can be accomplished by adding:
```
<meta http-equiv="X-UA-Compatible" content="IE=edge">
```
and it is always good to include the polyfill library in order to support IE:
```
<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>
```
before any script.

Combine the answers of RooiWillie and MohD
and remember to run your app with administrative right.

var appName = System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe";

RegistryKey Regkey = null;
try
{
    int BrowserVer, RegVal;

    // get the installed IE version
    using (WebBrowser Wb = new WebBrowser())
        BrowserVer = Wb.Version.Major;

    // set the appropriate IE version
    if (BrowserVer >= 11)
        RegVal = 11001;
    else if (BrowserVer == 10)
        RegVal = 10001;
    else if (BrowserVer == 9)
        RegVal = 9999;
    else if (BrowserVer == 8)
        RegVal = 8888;
    else
        RegVal = 7000;

    //For 64 bit Machine 
    if (Environment.Is64BitOperatingSystem)
        Regkey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(@"SOFTWARE\\Wow6432Node\\Microsoft\\Internet Explorer\\MAIN\\FeatureControl\\FEATURE_BROWSER_EMULATION", true);
    else  //For 32 bit Machine 
        Regkey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(@"SOFTWARE\\Microsoft\\Internet Explorer\\Main\\FeatureControl\\FEATURE_BROWSER_EMULATION", true);

    //If the path is not correct or 
    //If user't have priviledges to access registry 
    if (Regkey == null)
    {
        MessageBox.Show("Registry Key for setting IE WebBrowser Rendering Address Not found. Try run the program with administrator's right.");
        return;
    }

    string FindAppkey = Convert.ToString(Regkey.GetValue(appName));

    //Check if key is already present 
    if (FindAppkey == RegVal.ToString())
    {
        Regkey.Close();
        return;
    }

    Regkey.SetValue(appName, RegVal, RegistryValueKind.DWord);
}
catch (Exception ex)
{
    MessageBox.Show("Registry Key for setting IE WebBrowser Rendering failed to setup");
    MessageBox.Show(ex.Message);
}
finally
{
    //Close the Registry 
    if (Regkey != null)
        Regkey.Close();
}
