Meeting Registration

I have set up a meeting and required registration.  This is working for the majority of people but I have a few that gets an email message saying they can't register and try a different email.  After they have tried several different emails, they contact me for assistance.  I asked them to login to their zoom account then try to register but this has failed to solve the problem. 

Is there any way I can register them from my screen?  I see how to manage but that only lets me either automatically approve or manually approve.  It does not get the ability to input a registration.

assistance please on how to register these people.

thanks
