Failed while processing WebSites

Hi Oler.

I have problems installing a website:

ConfigureIIs7Exec:  Entering ConfigureIIs7Exec in C:\Windows\Installer\MSIB01E.tmp, version 3.11.2318.0

Error 26002. Failed while processing WebSites.   (-2147024774         )

My code:

new IISVirtualDir
{
  Name = "O2k-Web-VirtualDir",
  WebSite = new WebSite("O2k-Web")
  {
    InstallWebSite = true,
    Description = "O2k-Web",
    Addresses = new[]
    {
      new WebSite.WebAddress
      {
        Address = "[SERVER_IP_ADDRESS]",
        Attributes = new Attributes
        {
          { "Port", "[SQL_PORT]" }
        }
      }
    }
  }
}

What was generated:

<Component Id="Component.VirtDir.INSTALL_LOCATION_WEB_CLIENT.73b54ea9868e40a2992c358ffbba5f" Guid="*-*-*-*-*" Win64="yes" KeyPath="yes">
  <iis:WebVirtualDir Id="VirtDir" Alias="O2k-Web-VirtualDir" Directory="INSTALL_LOCATION_WEB_CLIENT" WebSite="WebSite">

  </iis:WebVirtualDir>

  <iis:WebSite Id="WebSite" Description="O2k-Web" Directory="INSTALL_LOCATION_WEB_CLIENT">
    <iis:WebAddress Id="WebSite_Address1" IP="[SERVER_IP_ADDRESS]" Port="[SQL_PORT]" />
  </iis:WebSite>
  <RemoveFolder Id="INSTALL_LOCATION_WEB_CLIENT" On="uninstall" />
</Component>

This error is observed only on version 1.9.1. I rolled back to version 1.6.4.3, and there is no such error.
What was created by version 1.6.4.3:

<Component Id="Component.INSTALL_LOCATION_WEB_CLIENT.VirtDir" Guid="*-*-*-*-*" Win64="yes" KeyPath="yes">
  <iis:WebVirtualDir Id="VirtDir" Alias="O2k-Web-VirtualDir" Directory="INSTALL_LOCATION_WEB_CLIENT" WebSite="WebSite">
    <iis:WebApplication Id="MyWebAppWebApplication" Name="MyWebApp" />
  </iis:WebVirtualDir>

  <iis:WebSite Id="WebSite" Description="O2k-Web" Directory="INSTALL_LOCATION_WEB_CLIENT">
    <iis:WebAddress Id="WebSite_Address1" IP="[SERVER_IP_ADDRESS]" Port="[SQL_PORT]" />
  </iis:WebSite>
  <RemoveFolder Id="INSTALL_LOCATION_WEB_CLIENT" On="uninstall" />
</Component>

Looks like a long ID: Component.VirtDir.INSTALL_LOCATION_WEB_CLIENT.73b54ea9868e40a2992c358ffbba584f

To solve the problem, I used: Compiler.AutoGeneration.ForceComponentIdUniqueness = false;

It is an interesting one.

If the problem indeed caused by the too long component ID then indeed ForceComponentIdUniqueness = false may shorten it. Though it is disabled by default anyway:

BTW there are also other ways of controlling the ID allocation. You can pass the explicit ID for dir:

new Dir(new Id("AdminWebDir"), "AdminWeb",
        new IISVirtualDir
        {
            Name = "MyWebApp",
. . .

will generate

<Component Id="Component.AdminWebDir.VirtDir" Guid="6fe30b47-2577-43ad-9095-1861c12f314b" KeyPath="yes">
<WebVirtualDir Id="VirtDir.2" Alias="MyWebApp2" Directory="WebDir" WebSite="WebSite.1" xmlns="http://schemas.microsoft.com/wix/IIsExtension">
  <WebApplication Id="Test2WebApplication" Name="Test2" WebAppPool="MyWebApp2_AppPool" />
</WebVirtualDir>

There is even another way of controlling Component.Id directly but it is currently is not enabled for IISVirtualDir. That's why I have marked this post as enhancement and in the next release controlling Component id will also be possible via IISVirtualDir attributes:

new Dir("AdminWeb",
        new IISVirtualDir
        {
            Name = "MyWebApp",
            AttributesDefinition = "Component:Id=Component.AdminWeb"
