I just tried to create a Windows Firewall exception, but my semantics were undoubtedly incorrect.
I then tried turning off Windows Firewall and the Failed to connect to XBMC error still persists.

.Net Framework 4.6 has been deleted. .Net Framework 4.5.1 has been installed
VoxTools had been installed, I neglected to document that step.
I created a firewall exception for VoxCommando the first time you I ran it.
I am NOT on a private network.
Kodi is actually running and running on the same PC as VoxCommando when I try to "Test HTTP Connection" from the xJson plugin settings.
I double checked my Kodi settings for the web, remote control.
I just opened Windows Firewall and I do NOT see that a firewall exception has been created. I have done
some research into creating an exception but the directions are pretty obtuse! I have TeamViewer installed on
my PC. If anyone would be willing to connect via a TeamViewer session and create a firewall exception, I think that would solve the problem. Why a firewall exception was not created after multiple VoxCommando installs eludes me.

Hi, I must have been having a senior moment when I installed VoxCommado 2.2.0.7 without .Net Framework 4.6. I installed VoxCommado in a folder on the Desktop of my PC running Windows 7 with all of the latest System updates.

Kodi 15.2 Web server Services-Settings:
Allow remote control via HTTP is enabled
Port is 8080
Username is xbmc

Kodie 15.2 Remote Control:
Allow remote control by program to this computer is enabled.

In VoxCommado  Plugins > XJson
IP is 127.0.0.1
HTTP Port is 8080
Username is xbmc
Other Settings
OSD Notification is checked
Alternates Notification is checked
Change events prefix (default: XBMC) is XBMC
Eport XML to Folder is .\XbmcPayloads

When i clicked on the Test HTTP Connection:
I received the error Failed to connect to XBMC

I moved VoxCommado 2.2.0.7 and repository.vc.zip to the Desktop and deleted the Folder.
I then installed .Net Framework 4.6 and repeated all steps above.
I still have the same error.
Any help would be much appreciated. I am anxious to be able to implement voice control to Kodi with VoxCommado.
