I'm trying to do an installer using wix 3.8. I can use custom properties to store my own input, but I'd like to use values that where inputs on a previously installed msi. Is there a way to accomplish such thing?.

推荐答案

要使您朝正确的方向，请在拳头MSI中添加(当然首先要使其适应您的需求):

To get you in the right direction add this (of course adapt it to your needs first) in your fist MSI:

<DirectoryRef Id="INSTALLDIR">
  <Component Id="RegistryEntries" Guid="{0AC76129-F8E2-47D3-B9FD-09B1E10A8541}">
    <RegistryKey Root="HKLM" Key="Software\Company123\App123" Action="create">
      <RegistryValue Type="integer" Name="SomeIntegerValue" Value="1" KeyPath="yes"/>
      <RegistryValue Type="string" Name="UserInput" Value="[USERINPUT]" />
    </RegistryKey>
  </Component>
</DirectoryRef>

不要忘记引用<Feature> <ComponentRef Id="RegistryEntries" />中的组件 安装时，请为属性[USERINPUT]分配一个值，例如msiexec /i your.msi /qb+ USERINPUT="the value to be saved in registry"

Don't forget reference the component in your <Feature> <ComponentRef Id="RegistryEntries" /> When you install assign a value to the property [USERINPUT] e.g. msiexec /i your.msi /qb+ USERINPUT="the value to be saved in registry"

然后在第二个MSI中添加如下内容:

Then in the second MSI add something like this:

   <Property Id="READREGISTRY">
       <RegistrySearch Id="USERINPUT_Value" Root="HKLM" Key="Software\Company123\App123" Name="UserInput" Type="raw" />
   </Property>

在安装过程USERINPUT=中输入的值/字符串将存储在第二个MSI的属性READREGISTRY

The value/string you entered during installation USERINPUT= will be stored in your second MSI in the property READREGISTRY

这是我的第二个msi日志:

Here a piece of log in my second msi:

PROPERTY CHANGE: Adding READREGISTRY property. Its value is 'testing registry wef wef wef w'.

根据安装的位置(可能是每用户"或每台计算机")，您可以将根"调整为HKCU(用于PerUser安装)，或者将其保留为HKLM(用于PerMachine).

Based on your installation where it might be Per User or Per Machine you may adjust the Root to HKCU for PerUser installs or leave it to HKLM for PerMachine.
