CefSharp 是一個非常不錯的cef封裝。但它依賴於VC++環境。
具體如下：
| Branch | CEF Version | VC++ Version | .Net Version | Status |
|---|---|---|---|---|
| master | 3202 | 2013 | 4.5.2 | Development |
| cefsharp/62 | 3202 | 2013 | 4.5.2 | Pre-Release |
| cefsharp/57 | 2987 | 2013 | 4.5.2 | Release |
| cefsharp/55 | 2883 | 2013 | 4.5.2 | Unsupported |
| cefsharp/53 | 2785 | 2013 | 4.5.2 | Unsupported |
| cefsharp/51 | 2704 | 2013 | 4.5.2 | Unsupported |
| cefsharp/49 | 2623 | 2013 | 4.0 | Unsupported |
| cefsharp/47 | 2526 | 2013 | 4.0 | Unsupported |
| cefsharp/45 | 2454 | 2013 | 4.0 | Unsupported |
| cefsharp/43 | 2357 | 2012 | 4.0 | Unsupported |
| cefsharp/41 | 2272 | 2012 | 4.0 | Unsupported |
| cefsharp/39 | 2171 | 2012 | 4.0 | Unsupported |
| cefsharp/37 | 2062 | 2012 | 4.0 | Unsupported |
於是我們在初始化cef前需要先檢測vc++環境情況。
通過檢測注冊表方式，具體實現代碼如下：
public static bool IsInstallVc2013x86()
{
try
{
Microsoft.Win32.RegistryKey uninstallNode = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall");
foreach (string subKeyName in uninstallNode.GetSubKeyNames())
{
Microsoft.Win32.RegistryKey subKey = uninstallNode.OpenSubKey(subKeyName);
object BundleProviderKey = subKey.GetValue("BundleProviderKey");
if (BundleProviderKey != null)
{
//HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{ 5e4b593b - ca3c - 429c - bc49 - b51cbf46e72a}
//HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{13A4EE12-23EA-3371-91EE-EFB36DDFFF3E} 中文版本
if (BundleProviderKey.ToString() == "{5e4b593b-ca3c-429c-bc49-b51cbf46e72a}")
{
return true;
// MessageBox.Show(displayName.ToString());
}
//if (BundleProviderKey.ToString() == "{f65db027-aff3-4070-886a-0d87064aabb1}") 英文版
//{
// return true;
// // MessageBox.Show(displayName.ToString());
//}
}
}
}
catch (Exception ex)
{
//LogTextHelper.Error(ex);
}
return false;
}
當為檢測到未安裝時，提示用戶安裝。
用戶選擇確認后，以管理員方式執行安裝文件。

Caveat: There's either a new 2017 registry convention being used, or it hasn't been finalized, yet. As I'm guessing the upper-most keys of: [HKEY_CLASSES_ROOT\Installer\Dependencies\,,amd64,14.0,bundle] and [HKEY_CLASSES_ROOT\Installer\Dependencies\,,x86,14.0,bundle]
are subject to change, or at least have different nested GUIDs, I'm going to use list the key that ends with a GUID.
