same here... also switched from the classic teams version to the new one.
when switching back to classic, unchecking the register button and then switching back again to newteams and check the register button there doesn't work... :/

'Your Internet Security setting prevented one or more files from being opened' The file is c:\windows\system32\reg.exe.
