Regarding How to increase the participants capacity form 100 to 200

Hi @escelectronics 

Unfortunately, there is no way to upgrade a meeting to 200 participants. The next available size you can purchase is the Large Meeting 500 add-on, which will increase your maximum capacity to 500 participants. Once that is done, be sure to assign the license to your profile, so that it will take affect on your meetings. 

Hope that helps and please make sure to mark the solution as accepted if this information is what you needed.
