The Geometer's Sketchpad 5

The latest major version of The Geometer's Sketchpad is version 5, first released in November 2009. The latest minor update is 5.06, which is a free update for version 5 users. If you already use version 5, when you download the latest version it will continue to use your existing license. For more details on minor updates, consult the Release Notes.

The Geometer's Sketchpad 4

The Geometer's Sketchpad Version 4 was first released in December 2001, and has been replaced by Version 5, described above. The last minor update to version 4 was 4.07, and version 4 users are encouraged to use that version until they can upgrade to version 5. Version 4.07 is a free update for all version 4 users. For more details on minor updates, consult their release notes.

4.07 Updates

The 4.07 update can be applied to existing installations of Sketchpad 4.0x, and is recommended for all of these installations. Download the updater appropriate to your platform and license. Note that updaters only work for the given type of license--you cannot use the Full Edition updater to update a Student Edition of Sketchpad. These updates apply only to English-language editions of Sketchpad released by Key Curriculum Press.

*Macintosh Users: If you are updating from 4.00, 4.01, or 4.02 and running Mac OS X, please see FAQ: Mac OS X for special installation instructions. As of 4.05, Macintosh Updaters will only update applications stored in folders named "Sketchpad." If you have renamed your application folder after Sketchpad was originally installed, or moved the application outside of its original folder, temporarily move it back into a folder named "Sketchpad" before updating.

Please note:
If your browser does not decompress updates automatically, you may need a decompression tool such as WinZip(for Windows) or StuffIt Expander(for Macintosh).
