Bundle installation requests unnecessary restart

[harper23]

I have upgraded an installation from WiX3 to Wix4.0.1. It contains 3 MsiPackage installer databases. If I install all three in a row, no restart is requested. But with the bundle I get the message "You must restart your computer before you can use the software" in the custom THM dialog.

How can I avoid this message? It is wrong, because the software can be used: all files are in place all registration values allow to use the .NET components with exposed COM interfaces. The message "you can use..." makes no sense at all after the uninstall operation.

Here is the bundle source code:

<?include FD_Defines.wxi?>
<Wix xmlns="http://wixtoolset.org/schemas/v4/wxs" xmlns:bal="http://wixtoolset.org/schemas/v4/wxs/bal">
  <Bundle Name="ProductManagement" Version="$(var.CurrentVersion)" Manufacturer="ACME" UpgradeCode="my-GUID-is-here">    
    <BootstrapperApplication>
      <Payload SourceFile="Banner_small.jpg" />
      <bal:WixStandardBootstrapperApplication LicenseUrl="" Theme="hyperlinkLicense" />
    </BootstrapperApplication>

    <WixVariable Id="WixStdbaThemeXml" Value="HyperlinkTheme.xml" />
    <Variable Name="checkboxCrawler" Type="numeric" Value="0" />

    <bal:Condition Message="This OS version is not supported." Condition="(VersionNT &gt;= v6.1)" />
    
    <Chain>
      <MsiPackage SourceFile="$(var.ProductManagementX86.TargetDir)ProductManagementX86.msi" InstallCondition="NOT VersionNT64 OR checkboxCrawler = 0" />
      <MsiPackage SourceFile="$(var.ProductCrawlerX86.TargetDir)ProductCrawlerX86.msi" InstallCondition="checkboxCrawler = 1" />
      <MsiPackage SourceFile="$(var.ProductManagementX64.TargetDir)ProductManagementX64.msi" InstallCondition="VersionNT64" />
    </Chain>

  </Bundle>
</Wix>

Some log files contain the word restart:
ProductManagementX64.msi

The log shows me no reason for the "restart necessary" message. How can I identify the reason of this message and suppress it?

Did you ever figure this mystery out?

As the log shows there is no restart required. The reason for the message was a changed behavior in the API interface to THM files.

The bundle doesn't come with a custom bootstrapper application. Only a the HyperlinkTheme.xml defines the UI. I assume that the 3.x framework had set the localized SuccessRestartText to an empty string. The 4.x framework requires that the VisibleCondition in the THM must be used.

This change was necessary in the UI theme:

From
<Text Name="SuccessRestartText" X="-11" Y="-51" Width="400" Height="34" FontId="3" HideWhenDisabled="yes" DisablePrefix="yes">#(loc.SuccessRestartText)</Text>
To
<Label Name="SuccessRestartText" X="-11" Y="-51" Width="400" Height="34" FontId="3" HideWhenDisabled="yes" DisablePrefix="yes" VisibleCondition="WixStdBARestartRequired">#(loc.SuccessRestartText)</Label>
Please note the change item name.

The VisibleCondition was already introduced in WiX 3. So it was a problem in the theme XML.

Yep, there were a few changes in thmutil v4 needing tweaks to custom themes.
