Cannot join meetings from launch anymore

Suddenly, I cannot join others' meetings anymore from launch.  I get the options to "download installation" (but I've had zoom for 3 years), and once or twice that worked.  Not every time.  I've had to join from my "browser" and it seems some things are then disabled, like saving the chat.  So very frustrating and I've been late to several meetings now.  Help!!  (I have zoom pro).
