我正在尝试将更新应用于已安装的应用程序(已在机器上多次安装)。据我所知，我在更新时将其传递给 .msi 实例的 ProductCode。
根据代码，这相当于:
// Leaving out my set of global parameters (for brevity), instance is first (:I1)
Installer.InstallProduct("FullNameOfMsiFile", @"MSIINSTANCEGUID={GUISDF-F5FD-4333-9D02-F0B72E048AB6} TRANSFORMS="":I1""");
当我尝试这个时，我得到一个 InstallerException 告诉我“系统策略禁止此安装。请联系您的系统管理员”。调用 .msi 的程序具有提升的权限，如果未传递产品代码，则可以正常安装/更新程序。
当我尝试在命令行上传递 ProductCode(使用/n 传递 Product Code)时，也会发生这种情况。 安装/更新在没有 ProductCode 的情况下也能很好地工作，所以我认为这是问题所在。
我已经尝试了互联网上提出的几种解决方案，例如关闭 UCA 或寻找某种注册表项并进行更改，但都没有成功。
那么，为什么 Windows(Win 7 32 位)明确禁止我传递产品代码，有没有简单的方法来解决这个问题？
无论如何，如果这仅在用户手动更改某些设置后才有效，那么我的好安装程序就有严重的问题，因为它意味着安装/更新没有任何大惊小怪。
编辑以回答塔菲特的问题:
更新是一次重大升级，通过WIX代码为每个实例生成一个新的ProductCode，因此每个实例都有自己的升级代码(对于实例来说是唯一的):
<Property Id="InstanceId" Value="Default"/>
<InstanceTransforms Property="InstanceId">
<Instance Id="I1" ProductCode="*" UpgradeCode="{GUID-2B92-407D-A609-C8DD9A0CF09C}" />
<Instance Id="I2" ProductCode="*" UpgradeCode="{GUID-85B4-4C68-B687-EBE02F282C2D}" />
<!-- further possible instances here, removed for brevity -->
</InstanceTransforms>
为每个实例存储产品代码，因此在尝试升级时我知道要为实例传递哪个产品代码。
编辑编号2:
EventLog 不是很有启发性，它只有三个属于不工作升级的事件(一个是 msi 启动，一个是创建恢复点，然后一个是安装程序事务停止，但没有说明原因)
.msi 的日志刚刚停止并显示错误代码 1625，这意味着系统策略拒绝安装。我真的不知道这些是什么政策以及如何处理它们。
