I accidentally installed Teams personal and now I cannot install Team work!

I somehow foolishly installed Microsoft teams person in a computer I had to wipe because of a problem and now cannot uninstall it to reinstall teams work. (They are right next to each other and look very similar. Even though if you try to put a Teams work email into teams personal it rejects it) Even more foolishly I cannot remember how if fixed it last time it happened except that teams personal leaves behind a file that stops work teams that I have to delete…but which one… I thought the whole point of having add remove programs in windows was so that when it uninstalls a program it takes everything with it! Microsoft make the computer, the OS, and the program, and it is still a disaster!
