With the May 2024 Storyline 360 update (Build 3.88.32474.0), the 64-bit version of Storyline 360 is now the default.
According to Jesse Taber, engineering manager for Storyline 360, "Storyline has traditionally been a 32-bit application. The primary difference between 32-bit and 64-bit applications is the amount of system memory they can use. In Windows, 32-bit applications can access, at most, 4GB of memory, while 64-bit applications can access far more memory than any modern consumer-grade PC can accommodate."
Taber went on to state that "The primary benefit of targeting 64-bit processor architecture is the ability to use more system memory. When Storyline 360 opens a project file, it loads it all into memory. Very large projects, particularly those with many rich media assets, can experience issues opening, saving, and publishing in the 32-bit version of Storyline 360. Projects like this should be much more stable in Storyline 360 x64."
"Aside from memory usage, most authors will likely see performance on par with the 32-bit version of Storyline 360. While performance improvements were not a primary driver for creating Storyline 360 x64, we plan to invest more directly in performance improvements going forward," said Taber.
To install the update, start the Articulate 360 app, click the drop-down menu to the right of Storyline 360, and choose Install Update.
If the 64-bit version isn't working, you can easily restore access to the 32-bit version via the Articulate 360 preferences. Open the Articulate 360 desktop app, click the drop-down arrow in the upper right corner, and choose Preferences.
From the Legacy Access area, select Restore 32-bit Storyline 360 and then click the Save button.
