how to manually remove MSI installation?
提问by 5YrsLaterDBA
I am learning VS 2008 setup project to create install for our C# application. I made a mistake trying to delete the exe itself during the uninstall. Now I manually deleted the exe file but the entry still in Add Remove Program list. I try to install a fixed newer version but msi doesn't allow me to do so.
我正在学习 VS 2008 安装项目来为我们的 C# 应用程序创建安装。我在卸载过程中尝试删除 exe 本身时出错。现在我手动删除了 exe 文件，但该条目仍在添加删除程序列表中。我尝试安装固定的较新版本，但 msi 不允许我这样做。
How can I remove the old version manually (i can use regedit, no problem)? I am using XP machine. thanks
如何手动删除旧版本（我可以使用 regedit，没问题）？我正在使用XP机器。谢谢
EDIT: After I removed its subkey in that uninstall registry entry, I still cannot install my newer version.
编辑：在卸载注册表项中删除其子项后，我仍然无法安装我的较新版本。

If this is a proper small update / minor upgrade .msi file to fix an earlier version which couldn't uninstall, just install it with msiexec /i updated.msi REINSTALLMODE=vomus(and maybe also REINSTALL=ALL). The v of vomus will have Windows Installer replace the old package with the new, and then you can uninstall normally.
如果这是一个适当的小更新/次要升级 .msi 文件来修复无法卸载的早期版本，只需安装它msiexec /i updated.msi REINSTALLMODE=vomus（也许还有REINSTALL=ALL）。vomus的v会让Windows Installer把旧包替换成新包，然后就可以正常卸载了。
But of course all this is unnecessary these days with the ability to test on a virtual machine you can just revert...
但是当然，现在所有这些都是不必要的，因为能够在虚拟机上进行测试，您只需恢复...

Remove your install entry in registry here. You might need to find out the GUID from your setup project.
在此处删除注册表中的安装条目。您可能需要从安装项目中找出 GUID。
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall OR
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall
Check also DisplayName, it can be helpful when your product has defined friendly name.
还检查 DisplayName，当您的产品定义了友好名称时它会很有帮助。
