There are several adjustments you will need to do. Particularly with the PHP configuration on your server. You'll need to increase the maximum file upload limit and timeout limit.
Edit your php.ini file and set these values:
post_max_size = 200M
upload_max_filesize = 200M
max_execution_time = 599
max_input_time = 599
The above should set the file upload limit to 200MB instead of 2MB.
