如果您运行安装文件以在 Windows 11 或 Windows 10 计算机上安装程序并收到消息 -无法打开此安装包，请联系应用程序供应商以验证这是一个有效的 Windows Installer 包^{(This installation package could not be opened, Contact the application vendor to verify that this is a valid Windows Installer package)}，然后发布此帖子也许可以帮助你。

无法打开此安装包

如果您收到“无法打开此安装包”^{(This installation package could not be opened”)}消息，您可以执行以下操作：

1. 检查设置文件
2. 重新下载安装文件
3. 取消阻止文件
4. 暂时禁用安全软件
5. 更改下载位置
6. 使用管理员帐户
7. 运行 Windows 更新
8. 重新注册Windows Installer引擎
9. 检查Windows Installer 服务^{(Windows Installer Service)}的状态。

让我们来看看这些建议。

1]检查设置文件

检查安装文件^{(setup file)}是否适用于您的Windows 版本 – 32 位^{(Windows – 32-Bit)}或 64 位

2]重新下载安装文件

也许下载被中断或损坏。清除浏览器缓存并重新下载设置^{(re-download the setup)}并查看它是否有效。

3]取消阻止文件

右键单击^{(Right-click)}.exe文件^(.exe)，选择“属性”，然后单击“取消阻止^(Unblock)”按钮 - 如果文件已被阻止，则解锁文件。

4]暂时^{(Temporarily)}禁用安全软件

暂时禁用您的安全软件^{(security software)}，看看是否有帮助。但请记住，您的计算机将不受保护，如果设置包含任何恶意软件，您的计算机将很容易受到攻击。因此，只有在您完全信任下载的软件包时才这样做。

5]更改下载位置

如果您将设置文件保存在网络^(Network)上，您可能会看到此消息。将其保存到本地计算机并运行，看看它是否有效。

6]使用管理员帐户

也许需要管理员^{(Administrator)}权限。因此，然后登录到管理员^{(Administrator)}帐户或创建一个新的管理员^{(Administrator)}帐户，登录到管理员帐户^{(Administrator account)}，然后运行安装程序^(Installer)包。

7]运行Windows更新

运行 Windows Update^{(Run Windows Update)}以确保您运行的是最新版本的 Windows Installer^{(latest version of Windows Installer)}。或者，您的Windows Installer文件可能已损坏。扫描完成后运行系统文件检查器并重新启动。如果需要，可以在此处从Microsoft下载最新版本的^(Microsoft)Windows Installer。

8]重新注册Windows Installer引擎

您可能还需要考虑重新注册 Windows Installer 引擎^{(re-registering the Windows Installer engine)}。为此，请打开命令提示符^{(Command Prompt)}，键入以下内容并按 Enter：

msiexec /unregister

现在再次注册它，输入以下内容并按Enter。

msiexec /regserver

9]检查^(Check)Windows Installer服务^{(Windows Installer Service)}的状态

运行services.msc以打开服务管理器^{(Services Manager)}并检查Windows Installer 服务^{(Windows Installer Service)}或msiexec.exe进程的状态。默认情况下，它的启动^(Startup)样式应设置为Manual。

Windows Installer Service 添加^{(Windows Installer Service Adds)}、修改和删除作为Windows Installer（*.msi、*.msp）包提供的应用程序。如果禁用此服务，任何显式依赖它的服务都将无法启动。

双击^(Double)Windows Installer以打开其属性^(Properties)框，然后单击“开始^(Start)”按钮启动该服务。单击^(Click)开始按钮 现在运行安装程序^(Start)，看看是否有帮助。

如果无法访问 Windows Installer 服务，^{(Windows Installer Service can not be accessed)}请参阅此帖子，如果您收到Windows 可能安装在不受支持的目录消息中，请参阅此帖子。

This installation package could not be opened message in Windows 11/10

If you run a setυp file to install a prоgram on your Windows 11 or Windows 10 computer and you receive a message – This installation package could not be opened, Contact the application vendor to verify that this is a valid Windows Installer package, then this post may be able to help you.

This installation package could not be opened

If you receive a “This installation package could not be opened” message, here are a few things you could do:

1. Check the setup file
2. Re-download the setup file
3. Unblock the file
4. Temporarily disable security software
5. Change download location
6. Use an Admin account
7. Run Windows Update
8. Re-register Windows Installer engine
9. Check the status of the Windows Installer Service.

Let us take a look at these suggestions.

1] Check the setup file

Check if the setup file is meant for your version of Windows – 32-Bit or 64-Bit

2] Re-download the setup file

Maybe the download was interrupted or got corrupted. Clear your browser cache and re-download the setup and see it it works.

3] Unblock the file

Right-click on the .exe file, select Properties and then click on the Unblock button – if the file has been blocked, to unlock the file.

4] Temporarily disable security software

Disable your security software temporarily and see if that helps. But remember that your computer will be unprotected, and if the setup contains any malware, your computer will be vulnerable. So do this only if you totally trust the downloaded package.

5] Change download location

If you saved the setup file on a Network, you may get to see this message. Save it to your local computer and run and see if it works.

6] Use an Admin account

Maybe Administrator rights are required. So then either log in to an Administrator account or create a new Administrator account, log into the Administrator account and then run the Installer package.

7] Run Windows Update

Run Windows Update to make sure that you are running the latest version of Windows Installer. Or then, maybe your Windows Installer file has been corrupted. Run System File Checker and reboot once the scan is completed. If you need to, you can download the latest version of Windows Installer here from Microsoft.

8] Re-register Windows Installer engine

You may also want to consider re-registering the Windows Installer engine. To do so, open Command Prompt, type the following and hit Enter:

msiexec /unregister

Now to register it again, type the following and hit Enter.

msiexec /regserver

9] Check the status of the Windows Installer Service

Run services.msc to open the Services Manager and check the status of the Windows Installer Service or msiexec.exe process. Its Startup style should be set to Manual, by default.

Windows Installer Service Adds, modifies, and removes applications provided as a Windows Installer (*.msi, *.msp) package. If this service is disabled, any services that explicitly depend on it will fail to start.

Double click on Windows Installer to open its Properties box and then click on the Start button to start the service. Click on the Start button Now run the setup and see if that helps.

See this post if Windows Installer Service can not be accessed and this one if you receive Windows might be installed in an unsupported directory message.
