Windows 11, Internet Explorer and HiWatch NVR

 Microsoft now loves MS Edge as much as loved MS Internet Explorer years ago and switch IE to Edge form time to time.

But HiWatch still love MSIE - you cannot watch cameras in any other browser.

It is annoying thing in W10, but it become a nightmare in W11 - you even cannot find how to run IE.

You can create vbs file to run IE -

CreateObject("InternetExplorer.Application").Visible=true
