mediavets: When I purchase the software I have also the PTP2.0 licensee, but hence it is not released yet I didn't work on it
No, it has not yet reached Final release form.
It is currently at Alpha 18 status, not far from a Beta release.
You can use your PTP 2.x license for production work at your own 'risk', PTP 2.x alpha 18 is not yet compklete and has some bugs, many others are doing so on that basis.
If you wish to experiment with PTP 2.x use the Contact form to ask Kolor to register you on the Kolor VIProom forum which has been set up to support testing and use of pre-release versions of PTP 2.x; there are currently over 500 people registered on that forumhttp://www.kolor.com/contact.html
When registered on the VIProom forum you will be able to access download links for PTP 2.x and receive peer support with input from the developers.
You can install PTP 1.8 and PTP 2,.x on the same system.
There is limited compatibility between projects developed in PTP 1.8 and PTP 2.x.
