Before you spend hours hunting drivers, consider this: The NAV50 has at most 2GB of RAM (most have 1GB soldered + 1GB slot). Windows 7 64-bit requires 2GB minimum and will run sluggishly. The 64-bit drivers for the graphics chip are unstable at best.
The better alternative: Install Windows 7 32-bit. Everything works out of the box from Acer’s official support page. Or, if you want a modern, light OS, try a 32-bit Linux distribution (like Linux Mint Xfce or antiX).
If Windows Update fails to find specific hardware, you can download the drivers directly. Since Acer rarely lists 64-bit drivers for this specific model, you must identify the hardware components and use the manufacturer's generic drivers.

7. Webcam & Card Reader
These are usually last. Some require an Acer-specific utility called “Acer Crystal Eye Webcam” – download from Acer’s NAV50 utilities section.
This allows you to connect to the internet via cable. The NAV50 usually utilizes an Atheros chip.
The Acer Aspire One NAV50 (often listed under the AO NAV50 series) relies on a mix of Intel Atom chipsets, Realtek audio codecs, and Atheros or Broadcom wireless adapters. Without the right drivers:
Windows 7 64-bit is particularly picky because many built-in drivers were designed for 32-bit systems. Manual installation is often required. Windows 7 64-bit is particularly picky because many
