I have a C# project in VS2010 and an installer file for it - but the installer project is lost so I am trying to reproduce it. 我在VS2010中有一个C＃项目，并且有一个安装程序文件-但是安装程序项目丢失了，因此我尝试重现它。

On the old installer, it presents the following screen if previously installed. 在旧的安装程序上，如果先前已安装，它将显示以下屏幕。

How can I make this happen for the new installer as well? 如何使新安装程序也能做到这一点？ I have tried to use the same UpgradeCode (found using the advice here , but it still does not appear. Even running the same installer twice doesn't show it so I am guessing there is an option somewhere..? 我试图使用相同的UpgradeCode（使用此处的建议找到，但仍然没有出现。即使两次运行相同的安装程序也无法显示该信息，所以我猜测某个地方有一个选项。

The installer is a signed executable (or at least a uniquely-identified executable) so Windows knows when the 'same' one is being re-run and can present the 'repair/remove' dialog. 安装程序是经过签名的可执行文件（或至少一个唯一标识的可执行文件），因此Windows知道何时重新运行“相同”的文件，并可以显示“修复/删除”对话框。

Your new installer, though for the same project, has a different signature - so to Windows, it's completely different to the earlier one and therefore you just get the 'install' dialog. 您的新安装程序（对于同一个项目）具有不同的签名-因此对于Windows，它与早期的安装程序完全不同，因此，您仅显示“安装”对话框。

I'm not an expert on the subject, but in principle you'd have to replicate the signature of the earlier installer in your new one. 我不是该主题的专家，但是原则上您必须在新的安装程序中复制早期安装程序的签名。 I don't know if that's possible, but if it is then your new installer will look like the old one to Windows and you'll get the 'repair/remove' options. 我不知道这是否可行，但是如果是这样的话，那么新的安装程序将看起来像Windows的旧安装程序一样，您将获得“修复/删除”选项。
