There is a possibility of unexpected failures occurring during the installation or upgrading of Endpoint Clients depending on how the environment is configured. Some of the more common causes on Windows machines are due to Data Execution Prevention (DEP), User Account Control (UAC), antivirus or other third-party monitoring applications, and Windows Firewall.

Listed below are the recommended environmental configurations to be made prior to installing the Forcepoint Endpoint on machines.

User Access Control (UAC):

1. Open Control Panel 
2. Search for UAC (Normally under Action Center > Change User Account Control Settings).
3. Set to Never Notify.

Data Execution Prevention (DEP):

1. Open the Control Panel
2. Click System.
3. Navigate to Advanced System Settings > Settings (Performance) > Data Execution Prevention.
4. Ensure DEP is only set to for essential Windows components/services only.

Windows Firewall:

1. Open the Control Panel.
2. Click Windows Firewall settings.
3. Ensure that Windows Firewall is turned off.

Anti-Virus Exclusions:

Antivirus scanning can degrade the performance of Forcepoint security components if the proper exclusions are not set prior to installation. See Excluding Forcepoint Endpoint from Antivirus Scanning for more information.
