SketchUp does not see internet connection even though IE is up-to-date and using Windows 10

Should not be. SketchUp uses the MSIE “WebBrowser Control” which is a library engine (DLL file) that can be used by applications to display web sites in a window frame. It does not load all the toolbars and menus and other junk that the full blown Internet Explorer executable application does.


(1) Do install all updates for MSIE via Windows Update (anytime they become available, even if you normally use some other browser to manually browse the web.)

(2) Clear out your Temporary Internet Files and cookies.
Control Panel > Internet Options > General (tab) >
Browsing History (section) > Delete… (button)

(3) With SketchUp not loaded, delete it’s “cookiejar.xmlandsession.dat” files in folder:

  • %AppData%/SketchUp/SketchUp 2016/SketchUp

(4) In a command prompt run command: ipconfig /flushdns
to flush the DNS resolver cache.

Try again.
