Some archive-extract programs cause errors when unzipping the Crowd archive file.

• Linux or Unix users can use any unzip program.
• Solaris users must use GNU Tar instead of Solaris Tar.
• Windowsusers should use a third-party unzip program like 7Zip or Winzip. If you do not have one, please download and install one before continuing:
  • 7Zip — Recommended. If in doubt, download the '32-bit .exe' version
  • Winzip
