No Conference Room App?

i installed asterisk and freepbx following this guide:

All is ok, but on my dashbord i have this issue:
No Conference Room App
Neither app_meetme nor app_confbridge is configured in Asterisk, conferencing, paging and other functionality will not work properly

What i have to do?
I saw in the advanced setting and i found Conference Room App.
Here i can set:

  • app_confbridge
  • app_meetme

Now i have the first selected but if i use app_meetme not change anything.

Can you help me to solve it?
Thank you
