Description

Hello, I have an automated E2E test project on Azure and have a build pipeline set up to run our test suite

I am trying to set up a release pipeline in order to run selected automated tests directly from Azure Test Plans, following this guide:
https://learn.microsoft.com/en-us/azure/devops/test/run-automated-tests-from-test-hub?view=azure-devops

My build pipeline publishes an artifact containing the test binaries and the release pipeline downloads the binaries artifact ok, also the automated test cases are associated to the case in the Test Plan

But when I go to run the test I get a 'hostpolicy.dll' library missing error (see error message / logs below)

I tried following the steps outlined in this response but have not been able to get it working but yet:
#2427 (comment)

Steps to reproduce

Expected behavior

Selected test(s) from Test Plans should run

Actual behavior

Test exits with error: 'hostpolicy.dll' required to execute the application was not found
