[wix-users] WixIIsExtension

[Carlos Sosa]

Hello, can someone please provide any direction on the WixIIsExtension<http://wixtoolset.org/documentation/manual/v3/xsd/iis/index.html>? Or some other way to fix the error:
I'm using:

<InstallExecuteSequence>

      <Custom Action="ConfigureIIs" Before="InstallServices"> IISMAJORVERSION <= "#7" </Custom>
      <!--*****************-->
      <Custom Action="CheckWebServerRoles" Before="ConfigureIIs">NOT Installed</Custom>
      <Custom Action="aspnetregiisi" After="ConfigureIIs">NOT VersionNT64</Custom>
      <Custom Action="aspnetregiisix64" After="ConfigureIIs">VersionNT64</Custom>

</InstallExecuteSequence>


ConfigureIIs works just fine
CheckWebServerRoles works too

But after that I get this:

MSI (s) (F4:4C) [15:16:29:580]: Hello, I'm your 32bit Elevated Non-remapped custom action server.
StartIIS7ConfigTransaction:  Failed to back up applicationHost, not found - continuing
MSI (s) (F4:54) [15:16:29:580]: Executing op: ActionStart(Name=RollbackIIS7ConfigTransaction,Description=Rolling back IIS Config Transaction,)
Action 15:16:29: RollbackIIS7ConfigTransaction. Rolling back IIS Config Transaction

Any help is appreciated.
