I've installed it & it works pretty well. All .ics files now open with IronCAD if I double-click them in Windows Explorer.
Nevertheless, you can't keep Microsoft down. Outlook comes up at the top of the "Open With..." menu and the next time I rebooted & started Outlook, all the .ics files switched back to calendar icons (but they still open in IronCAD when I double-click them.)
I guess Microsoft just knows better than we do - .ics just
has to be a calendar file.

Yes i know, thats why i made it as an install application and not a reg file, sometimes you need to run it every time you start windows.
sometimes its enough to rightclick on the .ics file and choose open with ironcad after you run icsReclaim, that helps sometimes.
Or try to set outlook to not check if it is the default app for email and calender files, works fore some versions of office.
