Path to be updated After every successful builds

When I am triggering the build pipeline,it will create an solution file(.sln). After it's execution it will automatically trigger the release pipeline,It will create the setup file of my application. I want to test my application after the installer creation by using the testcomplete test cases. Currently I have specified the static path of the installer. After every success running of release pipeline it will create a new installer with new vesion.Everytime the folder name is updated with new version. My problem is, I want to choose the latest installer in the latest folder(the folder name is updated with folder name every time) when I am triggering the pipeline.
