When I attempt to change my os using the texas instrument student software, I received a message stating I cannot switch my os to an older version. This is the only thing stopping me from converting my CX I to a CAS. Any help would be appreciated.
If nothing works then I might just have to find 4.5.0 versions to see if that works.
Apologize for short text, I am on time limit.
