If you purchased a new version meaning PD14 retail and installed it then it should be on that HP computer. Many people have problems finding and navigating to the software in win 10. That could mean that you have both the PD12 oem version and PD14 retail version installed on the pc.
There is no need at all to uninstall the old software. It just mean that one may need to get familiar with the win 10. I remember answering this question before for another user.
Try this: Start the search box In the lower left of the screen and type cyberlink and then hit the enter key. You will then find all the cyberlink software installed on your pc if this is the first time. Start the PD14 that you want. If this works then you need to find out how to setup the desktop like you want in win 10.
