# Install or update the license file

To install or update the license in P4 Admin without having to restart the P4 Server:

1. Copy the new license file to the P4ROOT directory. (See P4ROOT in the P4 CLI Reference.)

2. Start P4 Admin on the server machine.

3. On the P4 Admin Administration Home tab, select `Load new license file`.

4. Browse to the new license file and select it.

If the new license file passes all checks, the new license is in effect. However, if the Server's IP address or port has changed, you might see an error. If so, stop the server, copy the new license file to P4ROOT, and restart the server. If that does not solve the problem, see the page on Release and license information in the P4 Server Administration Documentation or go to the Perforce Support Center.
