I'm not sure what steps I should follow to claim my HP promotion.

Hey ocidemus, thanks for posting here today! 

Let's jump right into this! Did you buy your device new or pre-owned?

Also, did Dropbox come preinstalled on the device or did you download it yourself? Do you see any relevant pop-ups that would allow you to enable the promotion?

While you're at it, please take a closer look at this Help Center article, and let me know if this helps.
Keep me posted, and we'll take it from there! 

its a new device

i downloaded it myself but there was a app called dropbox promotion but it says an error .
i did not see any pop ups to enable .

 it pops up when I open dropbox promotion

Hey ocidemus, would you mind sending us another screenshot of this Dropbox promotion app you're talking about? How the icon appears for you, for example.

sure this app was came installed already 

but if this is not it let me know how to claim the traditional way

Thanks for that, ocidemus.

Can you check if there's a Dropbox icon in your task bar, like the steps to claim the promotion describe here?

it was not on the task bar

Hey ocidemus!

We're going to need some account-specific info in order to investigate further.

Reply back to me, and we'll take it from there. Thanks!

ok what info you need

Hey ocidemus, happy Monday!

Megan was referring to the email she sent you and I can see that you replied to her there, so she'll get back to you really soon in order to investigate this further.

Have a great week ahead!
