I'm trying to use the HP Wallart Suite having recently purchased an HP Latex but I can't seem to save any details for the Applications Center when registering my details. I follow the instructions, fill in the fields required, press save and it just resets the form back to what it was and says I need to add my printer information. So next I try to do that and same happens again. The page refreshes, the form resets and nothing saves. I have tried 4 different browsers and 2 different devices and I am having the same problem over and over again. Any suggestions? Feel like I'm either missing something or going crazy.

you need to login through print OS....contact your HP seller and make sure you are set up in Print OS

You can register 2 different ways - by either accessing Applications Center from within your printos account as @stephen7706 mentions (register at printos.com), or by creating a dedicated Applications Center account at www.hpapplicationscenter.com.

In either case, what you are creating first is a HP Account ID, and what should happen when you hit register is you get an email with an verification code to compete your account setup. Are you getting that code ?
