@lgorence Hello Liv, and anyone else who comes across this thread.
I discovered that the AlmaLinux 9 was not allowing the Mango 3 install to complete due to permissions. Even after making the mango user the owner of the /opt/mango folder
the install still failed at the last module and kept trying to restart itself over and over again.
I recursively set the execute permission on the mango folder for the mango user and the install completed and we were able to get to the log in screen and pick up the correct license file.
That seems to have been the crux of the whole install problem.
Cheers
Brian
