Can anyone give me a example of modifying windows environment system variables in WIX?

问题

I still don't know how to add the installdir into the PATH of the Windows System Variables after I went through the WIX tutorial.

I tried to use

  Environment Id='UpdatePath' Action='create' Name='PATH'  System='yes' Value='[INSTALLDIR]'

But there was no change in the Path after I installed the program. I can hardly find sample code of WIX anywhere. Please help me, thanks a lot!

回答1:

You should be able to use:

<Environment Id="PATH" Name="PATH" Value="[INSTALLDIR]" Permanent="yes" Part="last" Action="set" System="yes" />

This should add a new entry to the environment path, set to [INSTALLDIR].

Another thing to note is, Environment need to be placed inside a component with directory, e.g.

<DirectoryRef Id="TARGETDIR">
  <Component Id="Path" Guid="{xxx-xxx-xxx-xxx}">
    <Environment Id="PATH" Name="PATH" Value="[INSTALLDIR]" Permanent="no" Part="last" Action="set" System="no" />
  </Component>
</DirectoryRef>

Had the same exact problem, this have worked for me:

        <Directory Id="TARGETDIR" Name="SourceDir">
            <Directory Id="ProgramFilesFolder">
                <Directory Id="INSTALLFOLDER" Name="DataBaseds_Service_Installer" />
            </Directory>
        </Directory>

    <ComponentGroup Id="Components" Directory="INSTALLFOLDER">

      ...some components  
    </ComponentGroup>

    <DirectoryRef Id="TARGETDIR">
      <Component Id="MYSQL_PASSWORD" Guid="..."
        <Environment Id=HERE YOU CAN ADD THIS  :)/>
      </Component>      
    </DirectoryRef>
