For those that are having a problem with this warning and don't want to install Internet Explorer, I believe I solved it by adding a registry key for Internet Explorer that points to Chrome.  I can't guarantee it will work for you or what impact it may have but it got me past this annoying dialog window.

1. open regedit

2. add a folder called IEXPLORE.EXE in Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\

2. click on default and set it to your path to chrome. For me it was C:\Program Files\Google\Chrome\Application\chrome.exe

I hope that helps
