unable to install .exe files using win package module on a windows sever

Lots of things could be going wrong here.

What error do you get? Is there anything in windows event log? Change arguments and get the installer to write to a log file and look in that for problems.

Does installer need administrator privilege? May be you need to run using become runas - see https://docs.ansible.com/ansible/latest/plugins/become/runas.html?

Hope the above helps
