Just an update here, if you want to force Vizard to use IE11 as the embedded browser to display html and javascript, use the following code:
Code:
import _winreg
reg = _winreg.OpenKey(_winreg.HKEY_CURRENT_USER, r'Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION',0,_winreg.KEY_ALL_ACCESS)
_winreg.SetValueEx(reg,'VizHTMLViewer.exe',0,_winreg.REG_DWORD,11001)
