Let’s look at the file size logic. The legitimate Adobe InDesign CS6 installer is 1.2 GB. A "portable free" version is usually 180MB to 400MB. Where did the 800MB go?

What remains is a skeleton app. It might open an INDD file, but it cannot render complex transparency effects. Professional printers will reject files saved from these cracked portable copies because the metadata is corrupted.

If you have literally $0 and refuse to pay, use Scribus.

Using cracked software is a violation of copyright laws. While individual users are rarely sued, companies caught using unlicensed software face heavy fines and legal action.
