I have an XBAP on my website that used to work. I checked it today for the first time in ages and found it’s not working on Win7 x64 / IE9.

http://drewnoakes.com/code/wpf/flags/demo/demo.xbap

The error message I see is:

Startup URI: http://drewnoakes.com/code/wpf/flags/demo/demo.xbap
Application Identity: http://drewnoakes.com/code/wpf/flags/demo/demo.xbap#demo.xbap, Version=1.0.0.0, Culture=neutral, PublicKeyToken=6d8e235cc7c0267c, processorArchitecture=msil/demo.exe, Version=1.0.0.0, Culture=neutral, PublicKeyToken=6d8e235cc7c0267c, processorArchitecture=msil, type=win32

This application type has been disabled.

Can anyone explain what this means or provide information about how I might debug this further?

    Here is an explanation:

    Apparently you can undo the change IE9 made to URLACTION_WINDOWS_BROWSER_APPLICATIONS or you could change the zone for your site.
