What causes the following StateServerException exception to be thrown from the .NET NamedCache API?

Soss.Client.StateServerException: Unable to register AppName "/LM/W3SVC/1/ROOT" with StateServer: StateServer status code: -101: SOSS store access: cannot initialize store access module

This exception is thrown when the ScaleOut client libraries are unable to initialize. The most common causes of this problem are the following:
  • SOSS client libraries are unable to read the registry key at
    HKEY_LOCAL_MACHINE\SOFTWARE\ScaleOut_Software\StateServer
  • SOSS client libraries don’t have permission to access the installation directory (typically at C:\Program Files\ScaleOut_Software\StateServer).
  • If this is a full server installation of ScaleOut, it can occur if client libraries don’t have permission to read the soss_params.txt file (located in the installation directory).
  • If this is a remote client installation of ScaleOut StateServer, it can occur if client libraries don’t have permission to read the soss_client_params.txt file (located in the installation directory).

We're having this problem on one of our web servers after doing a restart. I checked all the permissions and they seem fine. Is there anything else that can cause this?
