# Endpoint Installation Guide
:::(Info) (Notice)
On **April 15th, 2025**, Catchpoint updated its Endpoint logging domain. This change may require customers to update policies and allow the new domain to pass through firewalls.
The domain name change will apply for new versions going forward.
The new Endpoint domain going forward is **e.3gl.net**. We suggest allowing/whitelisting the domain with a wildcard for script: ***.3gl.net**. You can continue using the Endpoint software which utilizes our previous domain: **r.3gl.net**.
Please reach out to your CSM and VE if you have any questions.
:::

9. Select whether you want to install PCap
When you install the software, it asks you to point the installer at the npcap folder. If you don't do that, the TCP Traceroute doesn't work.
That is the screen that appear during the installation. So if you dont install it, it wont work.
