Trellix Smart Installer fails with the error: 1321. The Installer has insufficient privileges to modify the file

Technical Articles ID: KB96567
Last Modified: 2023-06-16 04:41:32 Etc/GMT

Environment

ePolicy Orchestrator (ePO) - SaaS
ePolicy Orchestrator (ePO) 5.10.x
Trellix Agent (TA) 5.7.x, 5.6.x
Trellix Smart Installer

For environment information, see KB51573 - Supported platforms for Trellix Agent 5.x.

Problem

Under certain conditions, you might have to remove the TA manually. Possible reasons include the following:

A failed upgrade leaves mismatched files and stops the /Forceuninstall from removing the agent
Corruption of files in previously installed versions of TA
Third-party software conflicts

Cause

The Trellix Smart Installer installation page shows the following error:

Error 1321. The Installer has insufficient privileges to modify the file C:\Program Files\McAfee\Agent\x86\ComponentPointProduct.dll

The logged-in Windows user has the required permissions to install TA. However, you can still encounter this error. It happens when there are traces or remnants of a previously installed TA.

Solution

Before you try to remove TA manually, try to remove TA using frminst.exe and the /forceuninstall switch:

Run the frminst.exe /forceuninstall command:
1. On the affected computer, click Start, Run, and type one of the following commands:
  
  "c:\Program Files\McAfee\Agent\x86\frminst.exe" /forceuninstall
  
  "c:\Program Files\McAfee\Common Framework\x86\frminst.exe" /forceuninstall
  
  IMPORTANT: The path varies depending on the version of TA you install, and whether you install it as an upgrade or clean installation. Use Windows Explorer to determine the correct path.
2. To remove TA processes from memory and complete the deletion of files, restart the computer.
If step 1 doesn't work, use the Trellix Endpoint Product Removal tool to remove TA. For details, see KB90895 - Endpoint Product Removal tool to uninstall Trellix products.

NOTE: The command to remove TA is --accepteula --MA
