Agent un-install error in LEM 6.3.1

Updated September 15, 2016

Overview

Upgrading LEM (appliance) to version 6.3.1 allows the agents to be upgraded to 6.3.1 from LEM. A bug was discovered in that prevents un-installing the Windows agent from Windows Programs and Features.

Error message:

Could not find a valid Java virtual machine to load.
You may need to re-install a supported Java virtual machine.

 

This will be fixed in the next version of the agent.

Environment

LEM 6.3.1, and agent version 6.3.1

Cause 

The agent un-install cannot find the new 'sand-boxed' Java 8, so it cannot un-install the agent.

Resolution

There are two options to resolve this:

Option 1:

  • Use the LEM remote agent un-installer, which can be performed from a separate Windows machine, or from the computer that the agent is installed on, or
  • Re-install the agent over-the-top of the existing Windows agent, using the latest Windows agent installer (local installer or remote installer).
    a. Be sure to right-click on the installer and select 'runas administrator' so the installer has the permissions to perform the un-install.
    b. Windows Programs and Features will now be able to un-install the agent.
    Local agent installer
    Remote agent installer

Option 2:

  • Stop the LEM Agent Service on the node via Windows Service manager i,e Services.msc
  • Delete the C:\Windows\Syswo64\ContegoSPOP
  • Run the Remote agent installer using the Run as administrator
