我有一个安装程序，支持我们以前版本的升级：
<Product Id="*"
Name="$(var.ProductName)"
Language="1033"
Version="$(var.InstallerVersion)"
Manufacturer="$(var.Manufacturer)"
UpgradeCode="$(var.UpgradeCode)">
<Upgrade Id="$(var.UpgradeCode)">
<UpgradeVersion Minimum="$(var.InstallerVersion)" IncludeMinimum="no" OnlyDetect="yes" Property="NEWERVERSIONFOUND" />
<UpgradeVersion Minimum="5.0.0" IncludeMinimum="yes" Maximum="$(var.InstallerVersion)" IncludeMaximum="yes" Property="OLDERVERSIONFOUND" MigrateFeatures="yes" />
<UpgradeVersion Minimum="0.0.0" IncludeMinimum="yes" Maximum="5.0.0" IncludeMaximum="no" Property="OLDESTVERSIONFOUND" MigrateFeatures="yes" />
</Upgrade>
<InstallExecuteSequence>
<Custom Action="SetReInstallProperty" After="FindRelatedProducts">OLDERVERSIONFOUND OR OLDESTVERSIONFOUND</Custom>
<Custom Action="SetReInstallModeProperty" After="FindRelatedProducts">OLDERVERSIONFOUND OR OLDESTVERSIONFOUND</Custom>
<RemoveExistingProducts After="InstallInitialize">OLDERVERSIONFOUND OR OLDESTVERSIONFOUND</RemoveExistingProducts>
当我在 UI 模式下在旧版本 4.2 上运行此安装程序时，升级工作正常。但是当我使用 /q 在静默模式下运行它时，它会在维护模式下运行并尝试自行卸载。
这是日志的部分：

两个安装程序中的主要功能名称不同。当我将新版本中的功能名称更改为与 4.2 相同时，升级在静默模式下工作，但在 UI 模式下停止工作，并出现类似的日志：在 MigrateFeatureState 之后，所有组件都处于状态 Installed: Absent; 请求：空；行动：Null 和 REMOVE 设置为 ALL。任何想法为什么它表现得如此奇怪？
