It is important to clarify a significant technical and legal point before providing a write-up: Adobe Illustrator CS2 (version 12) was released in 2005, not 2011. The “2011” date often associated with CS2 refers to the end of its activation servers and the release of a “downgraded” version with serial numbers to keep it usable for existing owners.
There is no official product called “Adobe Illustrator CS2 20” (version 20 would be Illustrator CC 2017). The correct version number for CS2 is 12.0.
Here is the complete, accurate write-up regarding the Portable version of Adobe Illustrator CS2 (12.0) and the common misconceptions surrounding it.
The "20" in the title is a common typo or misinterpretation:

The "2011 Portable Adobe Illustrator CS2 20" is a myth wrapped in a typo. What actually exists are unofficial, risky, outdated repacks of a 2005 vector editor whose activation was disabled in 2011. While technically possible to run from a USB drive, the stability, security, and modern compatibility are disastrous.
Final verdict: Do not download pre-made portable CS2 repacks. Instead, use Inkscape Portable — it is safer, faster, handles high-DPI screens, and opens SVG files natively. If you absolutely need Adobe Illustrator’s exact workflow, install the legitimate (non-portable) Affinity Designer or subscribe to Illustrator CC, but leave CS2 in the museum where it belongs.
