exec failure can mean few reasons but it's happening during installation.  
the version you're trying out is pretty stale and there were some bugs related to both agent and endpoint.

most of them are described in this issue: [7.11 BC2 Elastic Agent on Windows 10 goes 'unhealthy' and doesn't report any in-UI logs to ES · Issue #23402 · elastic/beats · GitHub](https://github.com/elastic/beats/issues/23402)  
to see if it's endpoint related you may find endpoint installer and try running  
`./endpoint-security install --upgrade --resources endpoint-security-resources.zip --log stdout --log-level trace` this will give us a better details about what's going on
