Error uninstalling ADAudit Plus 5

Error uninstalling ADAudit Plus 5

I am having a problem uninstalling AD Audit plus trial from my Win 10 box. I get error message (attached) "Some files exist in the specified directory. Kindly provide a different location for installing ADAudit Plus 5.0" I have A/V disabled and running as an admin. Does anyone know what might be going on here?
