To add to this, starting with 10.5, Tableau Desktop is no longer supported on 32-bit operating systems. Here's a snippet from Upcoming changes to Tableau Desktop operating system requirements | Tableau Software
From time to time, it's important to reflect and assess the technologies we support. Like the floppy disk, it's time to say goodbye to 32-bit operating systems.
Starting with Tableau 10.5 this fall, new versions of Tableau will only run on 64-bit operating systems. Our upcoming release, Tableau 10.4, will be the last version of Tableau Desktop, Tableau Reader, and Tableau Public to support 32-bit Windows operating systems.
By focusing on 64-bit operating systems, we can deliver new product innovation faster and create experiences that better leverage modern hardware. Computers with 32-bit Windows operating systems are limited to 4 GB of memory, which can severely hinder memory-intensive processes like data analysis. In comparison, 64-bit computers can accommodate an almost limitless amount of memory, more than enough for even the most computationally intensive tasks. With the 64-bit version of Tableau Desktop, you can enjoy fast performance while executing memory-intensive tasks like running complex table calcs, plotting millions of data points, and integrating large data sets.
So, if you need a version after 10.5, you'll need to start looking to upgrade your laptop, unfortunately.
