Assembly Binding Log Viewer (fuslogvw) is not logging bindings for any version of the framework installed on my machine.
I tried using a custom log location, the default log location, the default category, and the native images category.
Assembly Binding Log Viewer worked a few months ago. I'm on a 64-bit machine and am running C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\NETFX 4.0 Tools\x64\FUSLOGVW.exe
