Yes. The PortableApps platform supports both 32-bit and 64-bit software. However, a 32-bit application (like CS3) has memory limitations—typically capped at utilizing around 3GB to 4GB of RAM, regardless of how much memory your modern 64-bit computer has. For complex vector illustrations with high-resolution raster effects, this memory cap can lead to crashes on modern hardware.
This seemingly niche keyword represents a powerful, repackaged version of Adobe’s legendary vector editor, converted into a portable application (using the PortableApps.com Format - PAF) that can run directly from a USB drive without installation. But what exactly is it? Is it legal? Does it work on Windows 10/11? And why is the “64-bit” tag so critical? Adobe Illustrator CS3 Portable -PAF- 64 Bit
If the portable version is a "full" modification, you would theoretically have access to these landmark features from 2007: Installation CS3 [CS3 is DEAD and gone] - Adobe Community Is it legal

While the concept of a "PortableApp" is legitimate, the distribution of proprietary software like Adobe Illustrator in this format is legally gray and often dangerous.
