这是另一种方式(您不需要任何工具):

Here's another way (you don't need any tools):

• 打开系统注册表并搜索 HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstall 键(如果它是 64 位机器上的 32 位安装程序，它可能位于 HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoftWindowsCurrentVersionUninstall 代替).
• 该键下列出的 GUID 是安装在这台机器上的产品
• 找到您正在谈论的那个 - 只需一步一步，直到您在右侧窗格中看到它的名称

• open system registry and search for HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstall key (if it's a 32-bit installer on a 64-bit machine, it might be under HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoftWindowsCurrentVersionUninstall instead).
• the GUIDs listed under that key are the products installed on this machine
• find the one you're talking about - just step one by one until you see its name on the right pane

您停止的这个 GUID 是产品代码.

This GUID you stopped on is the ProductCode.

现在，如果您确定重新安装此应用程序会顺利，您可以运行以下命令行:

Now, if you're sure that reinstallation of this application will go fine, you can run the following command line:

msiexec/i {PRODUCT-CODE-GUID-HERE}重新安装=全部重新安装模式=omus/l*v日志.txt

msiexec /i {PRODUCT-CODE-GUID-HERE} REINSTALL=ALL REINSTALLMODE=omus /l*v log.txt

这将修复"您的应用程序.现在查看日志文件并搜索UpgradeCode".这个值被转储到那里.

This will "repair" your application. Now look at the log file and search for "UpgradeCode". This value is dumped there.

注意:只有当您确定重新安装流程正确实施并且这不会破坏您安装的应用程序时，您才应该这样做.

NOTE: you should only do this if you are sure that reinstall flow is implemented correctly and this won't break your installed application.
