Are you basically at the point where you have your own keystore file ready to go and are just trying to find where to put it? If so:
1) Make sure your keystore file is named **keystore.jks**
2) Stop the AutoPass service (''HPE AutoPass License Server'' under Windows Services).
3) Find where your current keystore.jks file is. For example, mine is located here (yours should be very similar):
> C:Program FilesHPHP AutoPass
> License ServerHP AutoPass License
> ServerHP AutoPass License
> Serverconf
4) Backup/rename the old keystore file that's there (e.g., rename the old keystore.jks to keystore.jks.old).
5) Place your current/updated keystore.jks in this location.
6) Start the AutoPass service.
