## Symptoms

- * The Device Agent installation process stalls, preventing the full client package from installing.
* The "Upgrade NOW" button becomes unresponsive and fails to trigger the installation process regardless of user interaction.

## Cause

This issue stems from a communication conflict within the Endpoint Security Client UI when the Harmony Endpoint Portal upgrade installation settings are activated.

## Solution

Several **workarounds** are available:   
*Disable Installation Postponement*:

1. Navigate to the Harmony Endpoint Portal Settings.
2. Uncheck the "Install Upgrade" option to prevent users from postponing installation.

*Modify Force Installation Timer*:

1. Access Client Settings.
2. Reduce the "Force Installation" duration from the default 48 hours to approximately 2 hours.  
   This prevents extended installation stalls.

<br />

**Recovery Process**   
If the Device Agent client was previously installed with user postponement enabled, execute these commands as Administrator using the Command Line:

`reg delete "HKLM\SOFTWARE\CheckPoint\Endpoint Security\ZdxToDa" /v ZdxCall /reg:32 /f taskkill /f /im cpda.exe`

This sequence will restore functionality to the "Upgrade Now" button and allow the installation to proceed normally.
