Well that is strange. What version of Windows are you using? I am on Win 10 and always just "search" for remove app until the add/remove program icon comes up. I select it and it shows up as CMS Intellicad . . . . It then runs the uninstall and I'm good to go for the new version.
Two things I can suggest is to re-install the "old" build (the same one you have installed now) straight on top and see if it restores the un-install functionality. Be sure to backup your settings first, The other idea is if you have a system restore point or earlier backup.
