vSphere Web Client – You’ll need a new app to open this VMware-csd

While logging in to a vSphere Web Client (version 6.0) I received the following message:

“Do you want to allow this website to open an application on your computer?”

After clicking Allow the following message appeared:

"You'll need a new app to open this wmware-csd"

I am using Internet Explorer 11.447.14393.0 on a Windows 10 workstation.  As suggested on the vSphere Web Client Software Requirements page I am using a supported browser which already has the Adobe Flash Player integrated.

I was able to resolve this by installing the Client Integration Plug-in:

1. Log in to the vSphere Web Client
2. From the Help menu choose About VMware vSphere

5. Restart the browser
