: This was the final major version to support 32-bit operating systems.

Adobe Lightroom was initially released in 2006, a time when 32-bit Windows XP and Vista were standard. Early versions of Lightroom (versions 1 through 4) were widely available in 32-bit variants. These versions were lightweight and efficient for their time, catering to the hardware constraints of the mid-to-late 2000s.

Adobe officially ended 32-bit support years ago to prioritize the performance of 64-bit systems.

Note that Adobe Lightroom is no longer available in a 32-bit version, as most modern computers run on 64-bit architecture. The current versions of Lightroom (Lightroom Classic CC and Lightroom CC) are designed to take advantage of the latest technologies and provide optimal performance on modern computers.
