Cause

This error occurs due to registry corruption (not induced by the Innowera License Server) that leads to communication errors between Process Runner and Innowera License Server.

Solution

To resolve this issue, perform the following steps:

  1. Open the Command Prompt window with administrator privileges.
  2. Type netsh winsock reset.

If the error is not resolved, see http://support.microsoft.com/default.aspx?scid=kb;en-us;817571.

Note: The error mentioned in the Microsoft link is different from the one that is encountered in Process Runner, though the underlying cause is the same.
