Install Full Text search on existing instance

We have an existing sql server 2012 instance but without full text search.
before I add the feature, I want to know if it stops or restart the instance since it is for production.

thanks in advance.

The setup program restarts the target instance when installing full text search.

However, there's an easy way to find out: test it! Don't trust what I say: test it in your test environment.
