Q- I get an error when I try to to insert a url in PPT 2013/2016. Is there a fix?
A - PowerPoint 2013 blocks the webbrowser control from being inserted which prevents LiveWeb from functioning normally. Please visit this microsoft page to resolve this issue: Cannot insert certain scriptable ActiveX controls into Office 2013 documents

For PowerPoint 2016, the following registry keys need to be set, depending on your Windows operation system and Office to allow the browser control to be inserted.

On Windows 32-bit for 32-bit Office 2016

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\16.0\ClickToRun\REGISTRY\MACHINE\Software\Microsoft\Office\16.0\Common\COM Compatibility\{8856F961-340A-11D0-A96B-00C04FD705A2}]

"Compatibility Flags"=dword:00000000

On Windows 64-bit for 32-bit Office 2016 

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\REGISTRY\MACHINE\Software\Wow6432Node\Microsoft\Office\16.0\Common\COM Compatibility\{8856F961-340A-11D0-A96B-00C04FD705A2}]

"Compatibility Flags"=dword:00000000

On Windows 64-bit for 64-bit Office 2016

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\REGISTRY\MACHINE\Software\Microsoft\Office\16.0\Common\COM Compatibility\{8856F961-340A-11D0-A96B-00C04FD705A2}]

"Compatibility Flags"=dword:00000000

Q - How can I force the browser control to use a specific rendering engine?
A - The default rendering in the web browser control is IE7. If you have access to the server, you can change that by setting a meta tag on the html page to target the desired version of IE. Set the tag <meta http-equiv="X-UA-Compatible" content="IE=x" > in the HTML page you're showing. Replace x with the version number of IE you want to target. This forces the control to use the specified version.

Q - How can I force the browser control to use a specific rendering engine when I don't have access to the server.
A - You can still set the compatiblity local to the machine which will render the slideshow. Create the following registry key:

[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION]
"PowerPnt.exe"=dword:00001f40

Now launch PowerPoint and the web browser control will render in the mode you target. I've assigned the hex value to use IE8.0 above.
