Comment on Horizon Toolbox 2 by Shengbo

Tomcat uses 80 + 443 ports by default, which are the same with View Connection Server.
I suggest that you remove your Tomcat and use our msi file to install Toolbox again.
Can you please try the following steps?
1, Kill tomcat8.exe
2, Uninstall HorizonToolbox from Windows Control Panel
3, Restart the Connection Server
4, Install Horizon Toolbox with the msi file.
Let me know if meet new errors.
