This review evaluates the Prolific USB-to-Serial Comm Port Driver version 3.2.0.0, specifically its relevance and utility for users as of 2021. Review: Prolific USB-to-Serial Driver v3.2.0.0
Version 3.2.0.0 (dated July 31, 2007) has become a "legacy savior" for users of older serial devices. While officially superseded by newer versions like 3.9.x, this specific 2007 version is often the only way to make older or "unauthorized" PL2303 chips work on modern operating systems like Windows 10 and 11. Performance & Reliability
Legacy Compatibility: This version is highly recommended for older PL-2303HXA and PL-2303X chips that reached End-of-Life (EOL) and are no longer supported by modern Prolific drivers.
The "Code 10" Fix: It is widely used to resolve the "This Device Cannot Start (Code 10)" error caused by newer drivers intentionally disabling non-genuine or older chips.
Stability: Once successfully installed and "locked" against Windows updates, it provides a stable bridge for devices like Baofeng radios, GPS units, and industrial serial equipment. Ease of Installation
The Prolific USB-to-Serial Comm Port driver version 3.2.0.0 is an older driver, originally dated July 31, 2007, which is frequently used as a workaround to fix compatibility issues with certain USB-to-serial chips (often clones or discontinued models) that no longer work with newer drivers on modern operating systems like Windows 10 or 11.

Users often seek this specific version because newer "official" drivers may trigger a "Code 10" error or display a "Phased Out" message if they detect non-original or older Prolific PL-2303 chips. Downgrading to version 3.2.0.0 often restores functionality for these devices. Where to Download
Since this is an older version, it is typically found on enthusiast sites or manufacturer support pages rather than the main Prolific corporate site:
Enthusiast Sites: Sites like Miklor and VE7ED provide direct links to version 3.2.0.0 for radio programming and other legacy uses.
Manufacturer Support: Legacy support for specific hardware brands, such as Dell, may offer specialized installers, though they often host newer versions like 5.1.x or 5.2.x.
Official Prolific Site: You can access their current driver downloads at Prolific USA or via their Customer Login (using GUEST for both username and password) to see if they still offer legacy versions.
