I was trying to install 2024 on my Mac and kept receiving the same Error 630 with no explanation. I tried multiple times with no changes, spending about 2 hours on it. I finally uninstalled TT, reinstalled it and it took my license key with no error this time!
I'm not sure what's going on, but it is frustrating to spend hours just trying to get TT installed when I was expecting to be spending that time on my taxes!
Software is my background, so not sure how TT is putting out something where you aren't even able to get the license key to be successful!
