With the help of the following articles I have come up with a working installer in which a new AppPool can be created or an existing AppPool can be selected.
- Creating a Web Application Installer with WIX 3.5 and Visual Studio 2010–Part 1
- Web Application Installer in WiX
- WiX and DTF: Using a Custom Action to list available web sites on IIS
- Installing a Web Application to an Existing IIS Website using Wix3
In short: Create a Website element in your Product element:
<Product>
<iis:WebSite Id="SelectedWebSite" Description="[WEBSITE_DESCRIPTION]" Directory="INSTALLFOLDER" SiteId="[WEBSITE_ID]">
<iis:WebAddress Id="AllUnassigned" Port="80" />
</iis:WebSite>
</Product>
Create an Include WebSites.wxi with the following content:
<?xml version="1.0" encoding="utf-8"?>
<Include>
<Property Id="WEBSITE_DESCRIPTION">
<RegistrySearch Id="WebSiteDescription" Name="WebSiteDescription" Root="HKLM" Key="SOFTWARE\!(loc.CompanyName)\[ProductName]\Install" Type="raw" />
</Property>
<Property Id="WEBSITE_ID">
<RegistrySearch Id="WebSiteID" Name="WebSiteID" Root="HKLM" Key="SOFTWARE\!(loc.CompanyName)\[ProductName]\Install" Type="raw" />
</Property>
<Property Id="WEBSITE_PATH">
<RegistrySearch Id="WebSitePath" Name="WebSitePath" Root="HKLM" Key="SOFTWARE\!(loc.CompanyName)\[ProductName]\Install" Type="raw" />
</Property>
<Property Id="WEBSITE_VD">
<RegistrySearch Id="WebSiteVD" Name="WebSiteVD" Root="HKLM" Key="SOFTWARE\!(loc.CompanyName)\[ProductName]\Install" Type="raw" />
</Property>
<CustomTable Id="AvailableWebSites">
<Column Id="WebSiteID" Category="Identifier" PrimaryKey="yes" Type="int" Width="4"/>
<Column Id="WebSiteDescription" Category="Text" Type="string" PrimaryKey="no"/>
<Column Id="WebSitePath" Category="Text" Type="string" PrimaryKey="no" Nullable="yes"/>
<Row>
<Data Column="WebSiteID">0</Data>
<Data Column="WebSiteDescription">Dummy</Data>
<Data Column="WebSitePath"></Data>
</Row>
</CustomTable>
</Include>
Create the CustomAction described here.
Create a wxs file with your AppPool:
<?xml version="1.0" encoding="UTF-8"?>
<Wix
xmlns="http://schemas.microsoft.com/wix/2006/wi"
xmlns:util="http://schemas.microsoft.com/wix/UtilExtension"
xmlns:iis="http://schemas.microsoft.com/wix/IIsExtension">
<Fragment>
<Component Id="WebVirtualDirComponent" Guid="PUT-GUID-HERE" Directory="INSTALLFOLDER" KeyPath="yes">
<iis:WebAppPool
Id="YourAppPoolName"
Name="[VD][WEBSITE_ID]"
ManagedRuntimeVersion="v4.0"
IdleTimeout="0"
RecycleMinutes="0"
ManagedPipelineMode="integrated"/>
<iis:WebVirtualDir Id="VDir" Alias="[VD]" Directory="INSTALLFOLDER" WebSite="SelectedWebSite">
<iis:WebApplication Id="NotizBrowserWebApp" WebAppPool="YourAppPoolName" Name="[VD][WEBSITE_ID]" />
<iis:WebDirProperties Id="NotizBrowserProps" AnonymousAccess="no" WindowsAuthentication="yes" DefaultDocuments="-" Execute="yes" Script="yes" Read="yes"/>
</iis:WebVirtualDir>
</Component>
</Fragment>
</Wix>
