I'm located in the US and a native English speaker. But this is a user-to-user forum, not Adobe customer support which is located in India.
CS1, CS2 and CS3 are dead & gone. The activation servers were removed from service years ago. Even if you find an installer, it's impossible to activate the software.
CS4, CS5 and CS6 are on life support. But they can still be activated providing you have the following: 1. original media (disks or downloads) you received at purchase and a way to read them, 2. a legitimate serial number for that version, language and platform (Win/Mac), 3. an older operating system that can support legacy 32-bit apps. -------------------------- NOTE 1 : Creative Suite installers won't work on macOS Sierra, High Sierra or Mojave without terminal workarounds. See the help article below. https://helpx.adobe.com/creative-cloud/kb/install-creative-suite-mac-os-sierra.html
NOTE 3: Legacy Creative Suite is discontinued & unsupported. Use at your own risk.
