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_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall项(如果它是64位计算机上的32位安装程序，则可能位于HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall下).
• 该键下列出的GUID是此计算机上安装的产品
• 找到您要讨论的内容-一步一步，直到在右窗格中看到其名称为止

• open system registry and search for HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall key (if it's a 32-bit installer on a 64-bit machine, it might be under HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall 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

您在此GUID上停止的是ProductCode.

This GUID you stopped on is the ProductCode.

现在，如果您确定可以重新安装此应用程序，则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} REINSTALL =全部REINSTALLMODE =正常/l * v log.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".此值将转储到那里.

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

注意:仅当您确定正确执行了重新安装流程并且不会破坏已安装的应用程序时，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.
