HP pen problems

[anask]

I bought right now the HP active pen (active PEN 1MR94AA) from Amazon. 

I put the battery into and download the software "HP pen control" but the app tells me that "the app is not supported by your computer" and obviously the pen doesn't function.. what can I do? I already install all the Hp raccomandations and Windows updates, so I'm a little bit confused..

Thank you for posting on HP Support Community.

First, find the computer's Model name:

HP Notebook PCs - How Do I Find My Model Number or Product Number?

Next, search the document for a compatible stylus:

Which stylus is compatible?

HP PCs - Touchscreen Compatibility with Pen and Stylus

If there is an HP Active Stylus available for your model, it will be included in the document.

(Tip to find out the compatibility PEN) 

1. Open the document in your browser
2. Click open both (all) categories (business and consumer) to expand the lists
3. Examine the lists to find a match to your computer model
4. Product Name contain an “m”? Consider this to be the same as the model with no “m”.
   Example: HP Envy x360 15m-bp011dx is the same (and uses the same stylus) as HP Envy x360 15-bp011dx
5. Use CTRL-F to open the webpage search bar – type in the model type of your computer, leaving off the “HP” prefix and stopping just before OR just after the “dash” in the name. “Less is better”.
   Example: Spectre x360 15-   or   Spectre x360  or  even just Envy x360 (no size designator)
6. If a match is found, examine the results to determine if there is a pen for your model group
   Example: matches for Spectre x360 15 include model groups: Spectre x360 15-ap0xx, Spectre x360 15-bl0xx

Hope this helps! Keep me posted for further assistance.
