J,
Yes, the Haptek player is installed as part of the UltraHal installation. If you wish to use additional 3D characters you will need to purchase the Character Expansion Pack (very nominal cost).
You can try either demo versions.
Once you have paid for the full version, you will receive activation for your product (Hal 6.1).
If you do the removal methods as previously mentioned, you should be able to download and try the 6.1 demo or purchase it and the expansion pack. The product activation procedure has been automated and should work without a problem. If you still experience any difficulties, contact Robert Medeksza via forum email (click above on Members, locate his name...)
Good luck!
