@vipulsrivastava-qasource Please review the bug.

Based on the reported error seems that you have an Elastic Agent running from inside that directory. At that point it cannot be installed. Ensure that you have no Elastic Agent running in that directory, then run the install command.

@blakerouse while QA is re-testing this, I would ask if you think its useful to cite a ticket to make 'install' command more flexible or report better in the case it can detect an agent running in this case.

Rahul, regardless of the above, I wanted to ask if we can make sure we have a variation on this test case covered somewhere as:

• RDP to the endpoint and place the agent in C:/ProgramFiles directory
• Unarchive the agent
• Open powershell as admin and Execute ./elastic-agent install with default policy
  verify agent comes on line and is functional
• then execute the enroll command on the host in powershell to move it to a different policy:
  .\elastic-agent enroll adfasdfasdf.asdf:9243 adsfasdfsdf==
  verify it correctly changes to the new policy and comes up fine and is still functional
