WiX 3 Tutorial: Custom EULA License and MSI localization

In Archive Tags #imported #archived Published 15. 04. 2010 2 comments

In this part of the ongoing Wix tutorial series we’ll take a look at how to localize your MSI into different languages. We’re still the mighty SuperForm: Program that takes care of all your label color needs. :)

Localizing the MSI

With WiX 3.0 localizing an MSI is pretty much a simple and straightforward process. First let look at the WiX project Properties->Build. There you can see "Cultures to build" textbox. Put specific cultures to build into the testbox or leave it empty to build all of them. Cultures have to be in correct culture format like en-US, en-GB or de-DE.

WixCultures

Next we have to tell WiX which cultures we actually have in our project. Take a look at the first post in the series about Solution/Project structure and look at the Lang directory in the project structure picture. There we have de-de and en-us subfolders each with its own localized stuff. In the subfolders pay attention to the WXL files Loc_de-de.wxl and Loc_en-us.wxl. Each one has a <String Id="LANG"> under the WixLocalization root node. By including the string with id LANG we tell WiX we want that culture built. For English we have <String Id="LANG">1033</String>, for German <String Id="LANG">1031</String> in Loc_de-de.wxl and for French we’d have to create another file Loc_fr-FR.wxl and put <String Id="LANG">1036</String>. WXL files are localization files. Any string we want to localize we have to put in there. To reference it we use loc keyword like this: !(loc.IdOfTheVariable) => !(loc.MustCloseSuperForm)

This is our Loc_en-us.wxl. Note that German wxl has an identical structure but values are in German. 

<?xml version="1.0" encoding="utf-8"?>
<WixLocalization Culture="en-us" xmlns="http://schemas.microsoft.com/wix/2006/localization" Codepage="1252">
  <String Id="LANG">1033</String>  
  <String Id="ProductName">SuperForm</String>
  <String Id="LicenseRtf" Overridable="yes">\Lang\en-us\EULA_en-us.rtf</String>  
  <String Id="ManufacturerName">My Company Name</String>  
  <String Id="AppNotSupported">This application is is not supported on your current OS. Minimal OS supported is Windows XP SP2</String>
  <String Id="DotNetFrameworkNeeded">.NET Framework 3.5 is required. Please install the .NET Framework then run this installer again.</String>
  <String Id="MustCloseSuperForm">Must close SuperForm!</String>
  <String Id="SuperFormNewerVersionInstalled">A newer version of !(loc.ProductName) is already installed.</String>  
  <String Id="ProductKeyCheckDialog_Title">!(loc.ProductName) setup</String>
  <String Id="ProductKeyCheckDialogControls_Title">!(loc.ProductName) Product check</String>
  <String Id="ProductKeyCheckDialogControls_Description">Plese Enter following information to perform the licence check.</String>
  <String Id="ProductKeyCheckDialogControls_FullName">Full Name:</String>
  <String Id="ProductKeyCheckDialogControls_Organization">Organization:</String>
  <String Id="ProductKeyCheckDialogControls_ProductKey">Product Key:</String>
  <String Id="ProductKeyCheckDialogControls_InvalidProductKey">The product key you entered is invalid. Please call user support.</String>  
</WixLocalization>

 

As you can see from the file we can use localization variables in other variables like we do for SuperFormNewerVersionInstalled string. ProductKeyCheckDialog* strings are to localize a custom dialog for Product key check which we’ll look at in the next post.

Built in dialog text localization

Under the de-de folder there’s also the WixUI_de-de.wxl file. This files contains German translations of all texts that are in WiX built in dialogs. It can be downloaded from WiX 3.0.5419.0 Source Forge site. Download the wix3-sources.zip and go to \src\ext\UIExtension\wixlib. There you’ll find already translated all WiX texts in 12 Languages.

Localizing the custom EULA license

Here it gets ugly. We can override the default EULA license easily by overriding WixUILicenseRtf WiX variable like this: <WixVariable Id="WixUILicenseRtf" Value="License.rtf" /> where License.rtf is the name of your custom EULA license file. The downside of this method is that you can only have one license file which means no localization for it. That’s why we need to make a workaround. License is checked on a dialog name LicenseAgreementDialog. What we have to do is overwrite that dialog and insert the functionality for localization.

This is a code for LicenseAgreementDialogOverwritten.wxs, an overwritten LicenseAgreementDialog that supports localization. LicenseAcceptedOverwritten replaces the LicenseAccepted built in variable.

<?xml version="1.0" encoding="UTF-8" ?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
  <Fragment>
    <UI>
      <Dialog Id="LicenseAgreementDialogOverwritten" Width="370" Height="270" Title="!(loc.LicenseAgreementDlg_Title)">
        <Control Id="LicenseAcceptedOverwrittenCheckBox" Type="CheckBox" X="20" Y="207" Width="330" Height="18" CheckBoxValue="1" Property="LicenseAcceptedOverwritten" Text="!(loc.LicenseAgreementDlgLicenseAcceptedCheckBox)" />
        <Control Id="Back" Type="PushButton" X="180" Y="243" Width="56" Height="17" Text="!(loc.WixUIBack)" />          
        <Control Id="Next" Type="PushButton" X="236" Y="243" Width="56" Height="17" Default="yes" Text="!(loc.WixUINext)">
          <Publish Event="SpawnWaitDialog" Value="WaitForCostingDlg">CostingComplete = 1</Publish>
          <Condition Action="disable">
            <![CDATA[ LicenseAcceptedOverwritten <> "1" ]]>
          </Condition>
          <Condition Action="enable">LicenseAcceptedOverwritten = "1"</Condition>
        </Control>
        <Control Id="Cancel" Type="PushButton" X="304" Y="243" Width="56" Height="17" Cancel="yes" Text="!(loc.WixUICancel)">
          <Publish Event="SpawnDialog" Value="CancelDlg">1</Publish>
        </Control>
        <Control Id="BannerBitmap" Type="Bitmap" X="0" Y="0" Width="370" Height="44" TabSkip="no" Text="!(loc.LicenseAgreementDlgBannerBitmap)" />
        <Control Id="LicenseText" Type="ScrollableText" X="20" Y="60" Width="330" Height="140" Sunken="yes" TabSkip="no">
          <!-- This is original line -->
          <!--<Text SourceFile="!(wix.WixUILicenseRtf=$(var.LicenseRtf))" />-->
          <!-- To enable EULA localization we change it to this -->
          <Text SourceFile="$(var.ProjectDir)\!(loc.LicenseRtf)" />
          <!-- In each of localization files (wxl) put line like this:
               <String Id="LicenseRtf" Overridable="yes">\Lang\en-us\EULA_en-us.rtf</String>-->
        </Control>
        <Control Id="Print" Type="PushButton" X="112" Y="243" Width="56" Height="17" Text="!(loc.WixUIPrint)">
          <Publish Event="DoAction" Value="WixUIPrintEula">1</Publish>
        </Control>
        <Control Id="BannerLine" Type="Line" X="0" Y="44" Width="370" Height="0" />
        <Control Id="BottomLine" Type="Line" X="0" Y="234" Width="370" Height="0" />
        <Control Id="Description" Type="Text" X="25" Y="23" Width="340" Height="15" Transparent="yes" NoPrefix="yes" Text="!(loc.LicenseAgreementDlgDescription)" />
        <Control Id="Title" Type="Text" X="15" Y="6" Width="200" Height="15" Transparent="yes" NoPrefix="yes" Text="!(loc.LicenseAgreementDlgTitle)" />
      </Dialog>
    </UI>
  </Fragment>
</Wix>
 
Look at the Control with Id "LicenseText” and read the comments. We’ve changed the original license text source to "$(var.ProjectDir)\!(loc.LicenseRtf)". var.ProjectDir is the directory of the project file. The !(loc.LicenseRtf) is where the magic happens. Scroll up and take a look at the wxl localization file example. We have the LicenseRtf declared there and it’s been made overridable so developers can change it if they want. The value of the LicenseRtf is the path to our localized EULA relative to the WiX project directory. With little hacking we’ve achieved a fully localizable installer package.
 
The final step is to insert the extended LicenseAgreementDialogOverwritten license dialog into the installer GUI chain.
This is how it’s done under the <UI> node of course.
  
<UI>      
      <!-- code to be discussed in later posts –>

      <!-- BEGIN UI LOGIC FOR CLEAN INSTALLER -->
      <Publish Dialog="WelcomeDlg" Control="Next" Event="NewDialog" Value="LicenseAgreementDialogOverwritten">1</Publish>
      <Publish Dialog="LicenseAgreementDialogOverwritten" Control="Back" Event="NewDialog" Value="WelcomeDlg">1</Publish>
      <Publish Dialog="LicenseAgreementDialogOverwritten" Control="Next" Event="NewDialog" Value="ProductKeyCheckDialog">LicenseAcceptedOverwritten = "1" AND NOT OLDER_VERSION_FOUND</Publish>
      <Publish Dialog="InstallDirDlg" Control="Back" Event="NewDialog" Value="ProductKeyCheckDialog">1</Publish>
      <!-- END UI LOGIC FOR CLEAN INSTALLER –>


      <!-- code to be discussed in later posts -->
</UI>

 

For a thing that should be simple for the end developer to do, localization can be a bit advanced for the novice WiXer. Hope this post makes the journey easier and that next versions of WiX improve this process.
