Accessing a virtual desktop with Desktop Viewer in Citrix XenDesktop 5.6 briefly opens / flashes and closes

Problem

You’ve just deployed a new desktop catalog in Citrix XenDesktop 5.6 and attempt to access the desktop through the Web Interface server but the Desktop Viewer opens, flashes and then quickly closes:

Reviewing the event logs in the application logs of the virtual desktops show that Event ID: 9032 is logged with the following description:

Citrix ICA could not configure Thinwire and switch to the remote ICA display. This error is typically caused by a prior RDP connection being made to the workstation. Rebooting the workstation or logging in at the
console will fix this.

Solution

I found quite a few older posts for earlier version of XenDesktop but later realized that this was caused by the fact that I had installed the VMware Tools after installing the XenDesktop VDA (Virtual Desktop Agent) which obviously was the wrong order.  Simply uninstalling and reinstalling the XenDesktop VDA Agent corrected the problem.
