Я нашел решение, это от BalCompiler.cs
if (!String.IsNullOrEmpty(launchTarget))
{
this.Core.CreateVariableRow(sourceLineNumbers, "LaunchTarget", launchTarget, "string", false, false);
}
if (!String.IsNullOrEmpty(launchTargetElevatedId))
{
this.Core.CreateVariableRow(sourceLineNumbers, "LaunchTargetElevatedId", launchTargetElevatedId, "string", false, false);
}
if (!String.IsNullOrEmpty(launchArguments))
{
this.Core.CreateVariableRow(sourceLineNumbers, "LaunchArguments", launchArguments, "string", false, false);
}
if (YesNoType.Yes == launchHidden)
{
this.Core.CreateVariableRow(sourceLineNumbers, "LaunchHidden", "yes", "string", false, false);
}
if (!String.IsNullOrEmpty(launchWorkingDir))
{
this.Core.CreateVariableRow(sourceLineNumbers, "LaunchWorkingFolder", launchWorkingDir, "string", false, false);
}
if (!String.IsNullOrEmpty(licenseFile))
{
this.Core.CreateWixVariableRow(sourceLineNumbers, "WixExtbaLicenseRtf", licenseFile, false);
}
if (null != licenseUrl)
{
this.Core.CreateWixVariableRow(sourceLineNumbers, "WixExtbaLicenseUrl", licenseUrl, false);
}
if (!String.IsNullOrEmpty(logoFile))
{
this.Core.CreateWixVariableRow(sourceLineNumbers, "WixExtbaLogo", logoFile, false);
}
if (!String.IsNullOrEmpty(logoSideFile))
{
this.Core.CreateWixVariableRow(sourceLineNumbers, "WixExtbaLogoSide", logoSideFile, false);
}
if (!String.IsNullOrEmpty(themeFile))
{
this.Core.CreateWixVariableRow(sourceLineNumbers, "WixExtbaThemeXml", themeFile, false);
}
if (!String.IsNullOrEmpty(localizationFile))
{
this.Core.CreateWixVariableRow(sourceLineNumbers, "WixExtbaThemeWxl", localizationFile, false);
}
Теперь я могу клиентскую базу данных и полную установку с расширенным приложением Wix.
