When you click and expand a node, the following error message displays:

There was no endpoint listening at net.tcp://clsolwindn:17777/orion/npm/businesslayer that could accept the message.


All NPM versions


 This can occur when Microsoft updates uninstall a required C++ module.


  1. Refer to Microsoft Visual C++ requirements for NPM
  2. Identify the missing C++ Module and download it from Microsoft website.
