The HP Support Assistant download for Windows 11 and Windows 10 is a free 169.5 MB installer on HP’s support site. It installs HP’s own support app, which finds driver and firmware updates, runs troubleshooters and tracks your HP PCs and printers.
New HP desktops and laptops ship with the app already installed, so check the taskbar for its question-mark icon first. You can also install it on a PC from another brand to manage an HP printer.
This guide covers the official file, installing and checking it, ARM and Mac options, the newer HP app, updates, and fixes for HP Support Assistant not installing.
Which HP Support Assistant download do you need?
HP publishes one Windows installer for current PCs and points other devices elsewhere. Match your machine to a row.
| Your machine | What to get | Size |
|---|---|---|
| HP laptop or desktop on Windows 11 or Windows 10 (Intel or AMD) | HP Support Assistant 9.55.10.0 (sp174448.exe) | 169.5 MB |
| Non-HP Windows PC with an HP printer | HP Support Assistant 9 (sp174448.exe) | 169.5 MB |
| 32-bit Windows 10 | The same sp174448.exe covers 32-bit editions | 169.5 MB |
| HP PC with an ARM (Snapdragon) processor | HP app on the Microsoft Store | Store download |
| Chromebook on ChromeOS M99 or later | HP Support Assistant for ChromeOS extension | Browser extension |
HP states that HP Support Assistant is not supported on ARM devices. The HP app ships ARM64 and x64 builds, so it is the HP support tool for Snapdragon laptops.

- SoftPaq sp174448 release notes — supported Windows versions, changes and MD5 hash

How to verify the HP Support Assistant installer
HP lists an MD5 hash for every SoftPaq in its release notes. Compare it with your copy before you run the file.
- Open Terminal from the Start menu and run cd $HOME\Downloads .
- Run Get-FileHash .\sp174448.exe -Algorithm MD5 .

A newer SoftPaq has a new file name and a new hash. Check the matching release notes page on ftp.hp.com for the current value.
Which HP support app do you need for your Mac?
HP Support Assistant has no macOS build. HP’s Windows installer lists only Windows 10 and Windows 11 editions. The HP app covers Mac users instead.
| Your setup | What to install | Link |
|---|---|---|
| Mac with an HP printer | The HP app, which runs on macOS and handles printing, scanning and support | HP app overview on hp.com |
| Mac user who needs drivers for an HP PC | Look up the HP PC by model or serial number on HP’s driver page | HP Software and Driver Downloads |
| Mac user with an HP Windows PC nearby | Install HP Support Assistant on the PC itself | HP Support Assistant page |
Is HP Support Assistant free?
Yes, HP Support Assistant is free. HP preinstalls it on new HP desktops and laptops and offers the installer at no cost on support.hp.com. Optional HP services such as HP SmartFriend are sold separately, and the app itself costs nothing. A site that charges for the app, or bundles it inside a download manager, is not HP. Take the file from support.hp.com or ftp.hp.com only.
Choose between HP Support Assistant and the HP app
HP has merged HP Smart and myHP into a single HP app for printing, device settings and tech support. HP Smart is no longer available for download. HP Support Assistant stays a separate product and still gets regular updates, the latest released on August 25, 2026.
Install HP Support Assistant on an Intel or AMD HP PC. Install the HP app on an ARM PC, a Mac, or when you mainly manage an HP printer. HP Support Assistant delivers HP driver and firmware updates, troubleshooters and automated fixes for Windows PCs. The HP app runs on Windows 10 64-bit and Windows 11, including ARM64, plus macOS, iPhone and Android. Both are free and can sit side by side.
HP still hosts the older HP Support Assistant 8.8.34.31 (36.5 MB, May 2021, sp114036.exe) for 64-bit Windows 10. Use version 9 unless an old PC refuses it.
