Hello Betsy, I am having the same problem. I am trying to install QB 2021 (I already have QB 2020 on my computer, but I need to work on a client's file who has 2021). It is installed properly, but it always asks me to activate it, I follow the instructions, and then it loops back to the beginning. Did you successfully fix this problem for your client, and could you tell me how to fix mine?

I really appreciate any help you can provide.
