ASP.NET state service - The system cannot find the file specified.

I've had the above problem on my windows 2008 64-bit machine recently and the suggested fix http://support.microsoft.com/kb/911720 didn't work.

Basically, the problem is that the registry is wrong. So, the solution was to edit the registry...

1. Go to command prompt and type regedit


2. When regedit opens, locate HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aspnet_state


3. ImagePath Data was %SystemRoot%\Microsoft.NET\Framework\v2.0.50727\aspnet_state.exe so altered to %SystemRoot%\Microsoft.NET\Framework64\v2.0.50727\aspnet_state.exe


4. Go to Services and start ASP.NET State Service

Ta da!!!!
