This is a late and narrow response, but works well for me since I only need a module to manage the agent version on Windows hosts:

class {'::puppet_agent':
    absolute_source => 'C:\MyOrgName\Installers\openvox-agent-x64.msi',
    package_version => '8.19.2',
    require         => File['C:\MyOrgName\Installers\openvox-agent-x64.msi'],
  }

This seems to work because

puppetlabs/puppet_agent

gets the version from the

aio_agent_version

fact for the idempotency check and doesn't care about the installed package name. With this method it is your responsibility to get the correct installer version onto the node before you use it with

absolute_source

, hence the

require

. For my use case this was easier than switching to a different module.
