I want to have a link in Chrome e.g.
Open Link
that when you click on it in the Chrome Browser that it launches the link in an IE window.
Can anyone
Starting with Chrome 74, legacy browser support (LBS) is built into chrome. The behavior meets the needs you describe, i.e. (pun intended) certain URLs are opened in a new Internet Exploder window, and not in a tab in Chrome.
From Google's official site on LBS:
As an administrator, you can automatically switch users between Chrome Browser and another browser. Deploy Legacy Browser Support (LBS) and use policies to specify which URLs open in an alternative browser. For example, you can ensure that browser visits to the internet use Chrome Browser, but visits to your organization’s intranet use Internet Explorer®.
For older versions of Chrome (≤73), a separate install is needed, namely the "legacy browser support extension". The P.S. to the question explicitly excludes browser extensions, but the reason seemed to be that clicking on the link should open a separate IE window.
