Hello. My name is Michael. I can help you with your question.
There are detailed instructions on how to do the installation on a Windows 8 system on the following page:
That's as specific as I can be with the information that you have provided. But if this doesn't help, please let me know, along with more detail about your computer operating system and the problem you are having with the app.
What happens now? Will it not install? not start? Please be as specific as possible.
Is this on a Windows computer?
If so, please try right clicking and selecting run as administrator.
Also be sure you are logged into the HP store.
As I mentioned above, right click and select run as administrator.
it sounds like you have not installed the app yet.
Every file the instructions at this page?
