I know that there is the native IIS7 support in wix 3.5, but I have this strange error.
So, if IIS6 Management Compatibility for IIS7 is not installed, then new App Pool did not created in installation process. But if IIS6 MC is installed it works ok and new App Pool is created. The name of App Pool we define in dialog during installation.

This wix code is used for define app poll:

<IIs:WebAppPool Id="AppPoolId" Name="[APP_POOL_NAME]" />

This error I have if IIS6 MC for IIS7 is not installed:

WriteIIS7ConfigChanges:  Error 0x800700b7: Failed to add appPool element
WriteIIS7ConfigChanges:  Error 0x800700b7: Failed to configure IIS appPool.
WriteIIS7ConfigChanges:  Error 0x800700b7: WriteIIS7ConfigChanges Failed.

Wix version is Wix3.5.2519.0
