ICDm attempts to install a newer client version than is supported by the client OS

Products

• Endpoint Security Complete

Issue/Introduction

The environment has clients including Windows 7 and Windows 2008 R2. These operating systems only support up to 14.3 RU7. 

However the ICDm is trying to push newer versions of the client (RU9/ RU10) to these endpoints, resulting in error messages in LiveUpdate and the SEP installation log.  

Cause

Windows 7 and Windows 2008 R2 only support up to 14.3 RU7. For reference:

Windows compatibility with Symantec Endpoint Protection clients

Resolution

The workaround involves disabling the auto-upgrade option, and (manually) installing the latest version the client supports: 

1. Disable Auto-Upgrade in the System Policy

2. Export a 14.3 RU7 package instead, which *can* be installed on these two operating systems.
