Power BI Desktop, which is the authoring tool for creating Power BI reports and visualizations, is available in both 32-bit and 64-bit versions. The choice between the two depends on your system’s architecture and requirements. Here’s some information about the 32-bit version of Power BI Desktop:

1. Compatibility: The 32-bit version of Power BI Desktop is designed to work on 32-bit Windows operating systems. It can also be installed on 64-bit Windows, but it may have limitations in handling large datasets due to the memory constraints of 32-bit systems.

2. Memory Limitation: One of the main limitations of the 32-bit version is its memory usage. It can utilize up to 2 GB of RAM, which may restrict its performance when working with very large datasets or complex reports.

3. Compatibility with Add-Ins: Some third-party add-ins or custom extensions may have better compatibility with the 32-bit version of Power BI Desktop.

If you’re using a 32-bit Windows operating system or have specific compatibility requirements, you can download and install the 32-bit version of Power BI Desktop from the official Microsoft Power BI website.

However, if your system is 64-bit and you have the option to use the 64-bit version of Power BI Desktop, it’s generally recommended for better performance and the ability to handle larger datasets more efficiently.
