检测客户pc电脑端VC++环境并安装

CefSharp 是一个非常不错的cef封装。但它依赖于VC++环境。

具体如下：

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

于是我们在初始化cef前需要先检测vc++环境情况。

通过检测注册表方式，具体实现代码如下：

public static bool IsInstallVc2013x86()
       {
           try
           {
               Microsoft.Win32.RegistryKey uninstallNode = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWAREMicrosoftWindowsCurrentVersionUninstall");
 
               foreach (string subKeyName in uninstallNode.GetSubKeyNames())
               {
                   Microsoft.Win32.RegistryKey subKey = uninstallNode.OpenSubKey(subKeyName);
                   object BundleProviderKey = subKey.GetValue("BundleProviderKey");
                   if (BundleProviderKey != null)
                   {
                       //HKEY_LOCAL_MACHINESOFTWAREWOW6432NodeMicrosoftWindowsCurrentVersionUninstall{ 5e4b593b - ca3c - 429c - bc49 - b51cbf46e72a}
                       //HKEY_LOCAL_MACHINESOFTWAREWOW6432NodeMicrosoftWindowsCurrentVersionUninstall{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;
       }

当为检测到未安装时，提示用户安装。

用户选择确认后，以管理员方式执行安装文件。

Visual C++ 2017

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_ROOTInstallerDependencies\,,amd64,14.0,bundle] and [HKEY_CLASSES_ROOTInstallerDependencies\,,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.
