New installation on Windows 10 problem

Situation
When I start the setup I first see the “Optional Site ID Selection”. I continue through that. Then, I get the following error: ERROR: PHP mb_string extension missing. To continue, install and enable mb_string extension, then restart web server.

I have done that in the php.ini file and restarted the server, but it still is not working.

OpenEMR Version
6.0.0.

Browser:
Edge

Operating System
Windows 10 Pro

Logs
N/A Not installed yet

This is the first screen when I run the setup script:

Here is the second screen (I can only include one image per post as a new user):

Thanks so much! Worked perfectly!
