I can not start (initialise) report server status from reporting services configuration ma

I have reporting services installed on my machine and just a couple of days back every thing was working correctly until some thing i have no idea of happened and screwed up every thing. No i can not access report manager and report sever. When i open reporting services configuration manager, the server status is not initialised and results in following error in the computers event log.

Service cannot be started. System.IO.FileLoadException: Could not load file or assembly 'ReportingServicesNativeServer, Version=0.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. (Exception from HRESULT: 0x800736B1)

Accessing report manager from the browser also throws this exception.

I'm having the same problem and I was just wondering if you managed to get your report server working

Okay so I got it working.

I got this solution fromAaron Stebner's blog.

Create a batch file with the following commands:

cd %SYSTEMROOT%\WinSXS
for /D %%i in (*vc80*) do rd %%i /s /q
del manifests\*vc80* /q
cd policies
for /D %%i in (*vc80*) do del %%i\* /q

Run the batch file

Then run a repair install of SQL reporting services.

And it should come back.

On my side, i got it working by just un-installing and then re-installing reporting services.
