Issue/Introduction

I'm upgrading a Policy Server to 12.8, and I'd like to get a download link to update ArcotSiteMinderAdapter component in my current 6.0 version. I'm aware of this issue because the Policy Server 12.8 installer was reporting at run time the following message :

  The Upgrade Readiness utility has identified potential issues.
  Remove or upgrade (to a 64-bit version) the identified custom components after
  the upgrade completes. Starting the Policy Server without doing so will likely
  result in errors. See the documentation for more information about the
  utility.
