Our Windows software is distributed as compressed "zip" files. Windows XP can open these files by simply double-clicking on them. No additional software is required. There is no installer for Periodic Table or Alchemist's Challenge; simply drag the .exe from the zip archive to wherever you want on your Windows system. Then double-click the .exe to run the software. To uninstall, drag the .exe to the recycle bin.

Some features are disabled in Synergy Creations' Periodic Table for Windows, Alchemist's Challenge, and ChemDuet software until you register them ($12-25 for a single-user license).
