我们的WiX安装程序将.NET 4.0 WinForms应用程序部署到Windows Vista和7台桌面。该应用包含Portable Class Library,需要.NET patch(KB2468871)。我们需要安装补丁作为先决条件。有多种方法可以应用补丁:
使用来自a similar question的建议,我创建了一个CustomAction
来检查我发现的QFE(#1)在找到时返回true。
private static bool IsPatchAlreadyInstalled()
{
// If the patch is installed, we can find it using WMI
var query = new SelectQuery("SELECT HotFixID FROM Win32_QuickFixEngineering WHERE HotFixID = 'Q2468871' OR HotFixID = 'KB2468871'");
var results = new ManagementObjectSearcher(query).Get();
return results.Count > 0;
}
不幸的是,由于补丁是作为工具(#2)的一部分安装的,因此在我的开发机上失败了。我还没有目睹情况#3。
检测补丁是否已应用的更好方法是什么?
答案 0 :(得分:13)
Win32_QuickFixEngineering
不会返回所有更新。实际上,它只返回仅限于QFE的更新:
Microsoft Windows Installer(MSI)或Windows提供的更新 更新站点(http://update.microsoft.com)不会返回 Win32_QuickFixEngineering。
您所追求的更新是MSI补丁。使用 Microsoft.Deployment.WindowsInstaller
(又名DTF - Deployment Tools Foundation,WiX toolset的一部分)来查询应用的MSI补丁:
public static bool IsPatchAlreadyInstalled(string productCode, string patchCode)
{
var patches =
PatchInstallation.GetPatches(null, productCode, null, UserContexts.Machine, PatchStates.Applied);
return patches.Any(patch => patch.DisplayName == patchCode);
}
在这种情况下,KB2468871是.NET Framework 4更新之一。如果已在计算机上应用更新,则以下内容将返回true:
IsPatchAlreadyInstalled("{F5B09CFD-F0B2-36AF-8DF4-1DF6B63FC7B4}", "KB2468871");// .NET Framework 4 Client Profile 64-bit
IsPatchAlreadyInstalled("{8E34682C-8118-31F1-BC4C-98CD9675E1C2}", "KB2468871");// .NET Framework 4 Extended 64-bit
IsPatchAlreadyInstalled("{3C3901C5-3455-3E0A-A214-0B093A5070A6}", "KB2468871");// .NET Framework 4 Client Profile 32-bit
IsPatchAlreadyInstalled("{0A0CADCF-78DA-33C4-A350-CD51849B9702}", "KB2468871");// .NET Framework 4 Extended 32-bit

我使用以下片段(使用@KMoraz的产品代码)通过WiX Burn实现了这一点:

util
命名空间引用Wix Util Extension。您需要在根元素中添加xmlns:util="http://schemas.microsoft.com/wix/UtilExtension"
并引用WixUtilExtension.dll
。
如果需要,将自动下载安装程序。您需要将本地保存的安装程序文件保存在WiX项目的根目录中,其名称与SourceFile
指定的名称相同,但是它们不会添加到安装程序包中,因为Compressed
设置为no
。

我一直在玩类似的情况,发现@KMoraz的答案几乎是正确的。 (注意:@KMoraz,我会留下这个评论,但还没有代表!)
Microsoft.Deployment.WindowsInstaller
命名空间似乎是要走的路,但按产品代码过滤可能过于严格。我遇到了修补程序安装在计算机上但未与产品代码{F5B09CFD-F0B2-36AF-8DF4-1DF6B63FC7B4}
或{8E34682C-8118-31F1-BC4C-98CD9675E1C2}
关联的问题。
我的解决方案是使用PatchInstallation.AllPatches
,它返回系统上已安装补丁的未过滤列表,然后使用linq查找答案。
public static bool CheckForPatch()
{
return IsPatchAlreadyInstalled("KB2468871")
}
public static bool IsPatchAlreadyInstalled(string patchCode)
{
var patches = PatchInstallation.AllPatches.ToList();
patches.ForEach(x => Console.WriteLine("--found patch {0} for {1}",x.DisplayName,x.ProductCode));
return patches.Any(patch => patch.DisplayName == patchCode);
}
